*There wouldn't appear to be any contraption or way to open the door from the outside. Pushing and pulling would yield no results.*
Julie
Mevis sighs. At least this time his assumption was right, but still for the future it would be safer to not make such assumptions. He was once more at a road block, but at this point any idea is a good idea, even how stupid it sounded. The riddle mentioned something about one of the watchers could not speak, as it would reveal the truth, and this quest was focused on finding out the truth about this place. Yet two of the watchers may name the same name of their mother. Mevis guessed the the water pouring out of the two holes and sound it made were the brothers with the mother being the water. That would mean the third hole in the center was the one that kept the truth. To make it speak, he would have to find a way to get water out of there or perhaps in there. For now he had no way to get water out of there, so he would try the reverse, get water in there. He would fill his waterskin with water from the pool and them attempt to pour into the middle hole.
Denny
*Water would trickle into the hole, though start streaming out the bottom of the door. There was the thinnest opening at the bottom, and it showed the room was slightly at an angle, tilting towards the door Mevis was at.*
Julie
Alright, so looked like filling it up with water wasn't going to be possible, at least not with a small waterskin as the water would drain faster than he could fill up. One foolish idea crossed off. This all that he could do after all, for what he couldn't compensate with wit, he would try with dedication. He wasn't going to return empty handed, that much is for sure. Time to start from the beginning again. 
"Three stand, eyes on each other." Mevis was still pretty sure this meant the three holes, but wasn't too sure on how they had eyes on each other. 
"One is bound by the acts of another." He assumed that meant one of the holes would react or do something if one of the other holes were effected. He wasn't sure which hole though and how to make it trigger the reaction.
"Two may name the same name of their mother" Only idea that came to mind was that the two streams shared the same pool of water which could perhaps be called the mother as it was supplying the water. Not sure how this was a relevant clue though.

"Only two could call another watcher brother" Going back to the previous clue, this could mean that those two holes were supposedly 'brothers' as they come from the same mother or it could somehow mean two of the holes were 'sisters' instead of 'brothers' and the third hole was the brother. Like the last clue though, Mevis wasn't sure how this was a clue.
"One cannot speak, else truth would uncover" Mevis still suspects that this is the whole that isn't pouring water. If he could somehow get water to pour out of it then the 'truth' about this door would be revealed. But he had no idea how to currently do that.
"Three stand, eyes on each other" Seems to be a repeat of the initial statement. He was pretty sure there was no deeper meaning here as he had read riddles in books that sometimes repeat certain phrases for dramatic effect or to keep a rhyme going.

"One must die, so take your choice" He wasn't sure what it meant for a stream to die, or what exactly 'One' was, but Mevis suspected he had to stop one of the streams or perhaps empty the pool to make it 'die'. 
"We will tell by just the noise" Well, the pouring of the water into the steam was the only thing Mevis was really hearing right now. If he were to stop the stream then there would be silence and that would be easily recognizable by sound. But perhaps there was some other sound in the cave. He was heavily relying on sight for the past few clues after all, so this time Mevis closes his eyes and tries to focus on the sounds of the cave.
Denny
*The water was streaming from the two larger holes, loudly splashing into the pool of water as ripples went across the pools, making small waves coasting on the edges. The sound of the water coming through the holes itself was an interesting one, as the water was running over the glass tube, making a slight whistling noise. The sound of running water was heard from the small hole, though muffled, as it came form the exterior of the glass tubes inside.*
Julie
Well that confirmed Mevis idea that the water was causing the noise. But what can he do to stop it from flowing? He recalled that with his thermal vision that some of the tunnels in the pool were warmer than the rest and the water coming out was also warm. Maybe those tunnels were cycling the water back? But he had nothing to plug such large tunnels. He would look at the holes that were pouring water. The riddle said he had to kill one, but the only way Mevis could think of to create silence is to plug those two holes. Well he may as well try it, it wasn't like he had anything to lose from trying. 
He would take of his shirt and pull the Oni Skull Mask from his bag and wrap the shirt around it. He apologized for mishandling the skull in such a way, but knew he wouldn't receive forgiveness from his best friend regardless. He would place it over the right hole in hopes of plugging it. He would then empty his backpack of any valuables, fill it with whatever rocks he can find in the cave and try to plug the left hole with it. Worst case scenario he was going to end up with a wet backpack and shirt, but only a small price to pay if it is able to solve this riddle.
Denny
*When the first hole began to be blocked, the water pressure increased notably both in the small gaps left and in the left spout. Upon covering the left hole, the water was quickly streaming out of small gaps left in the hole. It was difficult to create a perfect seal, after all. However, the noise was considerably quieter. Well, from outside. From the small hole, the water could be heard rushing even louder, and even the pool began to dip a little bit in depth without the streams. Then, came the soft cracking noise of the glass tubes inside, straining under the pressure of the water.*
Julie
Mevis wasn't sure if what was that cracking was a good or bad thing, but it was at least something. He was already in this deep. He would try to support the plugs with his hands if he could so they don't go flying out from the water pressure. He could only hope he was doing the right thing. If instead he broke whatever was suppose to be here, well, it would be clear that he wasn't skilled enough to rise up the ranks yet and would have to learn from this experience.
Denny
*Only a few seconds later, with Mevis blocking the hole more fully, the glass tube within would crack and shatter. The water would instantly stop coming from the right hole, now streaming out of the bottom of the door.*

*With muffled grating of stone and moving of heavy weight behind the walls, the stone door would begin slowly rising.*
Julie
Mevis would look at the rising door in confusion. Is it suppose to be rising? Will it rise all the way up. He still didn't fully understand the riddle, but for now he decided to wait until the door rose as high as it could. After which he would go retrieve his bag, shirt, mask, and belongings and head inside to the room with the mannequins. He got a feeling he had only managed to get past the first challenge and there was more to come.
Denny
*After the door rose to the top, no longer impeding Mevis' progress, he could see into the room. One mannequin stood to the side, facing a mirror in the middle of the room. The mirror was tilted to reflect the figurine's image so that it appeared to be facing the door in the reflection. The hovering stance the reflected figure had was due to distortion at the bottom of the mirror, below its feet. On the other side of the room was a set of two wooden doors, still closed.*

*The floor of the room was covered in water due to the broken tube on the right, with the leftmost tube dripping water. In fact, in that tube was a large shape, something struggling against the rocks in the way. They seemed to be making slow progress.*
Julie
Mevis would try to wring as much water as he can from his bag and shirt. It felt uncomfortable. He made a mental note to bring extra pair of clothing for future trips. He would look over the room and let out a sigh of a relief. He could only guess that he was the first one to make it this far unless someone was coming here to replace the broken tubes. At least now he could figure out what was creating the hovering mannequin, but now there is another puzzle before him as there are now 2 doors before him instead of 1. He would try to walk around the room and see if there was any writing like in the last room or any clues at all. He would then suddenly notice a shape struggling in the tube and jump back in shock. 
What in the world was that? His heart was beating fast and his flight response was kicking in as he would take a few steps back. Is it the strange creature that was coming and entering here? What should he do? He wanted to run, he clearly had figured out a major piece of the puzzle so he wouldn't be returning empty handed. But what would a hero do? His would then close his eyes and clench his fists and force his body to calm down. Heroes don't panic, they are brave and selfless. He would take a deep breath and try to clear his thoughts. For now the creature seems to still be stuck among the rocks. With his speed he should be more than capable of outrunning it if things got dangerous. There is nothing to fear about getting closer to it. After reassuring himself he would cautiously approach the shape struggling in the tube to get a closer look at what it was.
Denny
*The water in the tube would be murky do to the bubbles formed by the movement and the natural amount of dirt in the water. However, getting closer, Mevis could see that it was an Uzhi attempting to push its way out of the tube. It pushed its face against the tube, finally seeing Mevis, then pulled back and started moving against stream of water, trying to move from this room to the one Mevis had not yet entered.*
Julie
Mevis would be surprised to see someone trapped in the tube, but would then attempt to call out to it
"Wait! Where are you going! Are you trapped?"
Denny
*The Uzhi's frantic movements wouldn't slow down, still struggling to fight against the water. It reached the end of the tube, now reaching and trying to pull itself out. It was going into the room with the two wooden doors.*
Julie
Mevis would attempt to follow the Ushi, running after it, still calling out to it
"W-wait! I don't mean any harm! Are you the adventurer that got lost here?!"
Mevis realized he should've probably asked for more details about this quest, he didn't even know how the lost adventurer looked like or if the other ones that had gone before him had clues. He had been too careless and now he is paying the consequences for it. He hoped with dedication he can at least recover from his blunder.
Denny
A very basic illustration

*The Uzhi would be leaving the tube now, leaving Mevis' sight. The wooden doors would be locked, though were only held by a latch and had some give when pushed and pulled. From behind the doors, there was a loud splash and the frantic splashing and wading of water.*
Julie
Mevis would be a bit surprised to see the door only being held by a latch. He thought there would be some other puzzle involved here involving the mirror and mannequin. He did say he would rather use his head than his fist to solve problems, but his fist was sadly much faster than his head and time is of the essence. He would take a few steps back from the door before charging forward at 40 mph with a flying kick in hopes of breaking it open.
Denny
*Mevis's strike broke the latch and flung the doors open, flying into the next room. In here, the floor would be lower, a few steps below the last room, and the water would be ankle depth. It would appear to be a tomb, but the stone coffin would not have a top. On either side of mevis, there's be water being magically lifted from the ground and into the tubes, seeming to work on some old magical machinery. To the left, under one of these arrangements, a purple Uzhi woman would be quickly running through the water. She was going from the wall to the coffin, looking at Mevis with wide eyes as she moved.*
Julie
"P-Please, don't run! I am unarmed, see! Please, talk to me!" Yells Mevis as he raises his arm to show that he is indeed unarmed and slowly walks toward her. He knew he was still capable of violence due to being a martial artists, but hoped the intention of the motion would get through.
Denny
*The Uzhi would slow to a halt, just a few feet away from the coffin. She looked anxiously from Mevis to the open door behind home, clearly frightened and wary. A few moments passed in the relative silence before she spoke.*
"You're not one of those paladin nutjobs, are you? From the sunshine guild or whatever?"
Julie
"Uh..." Mevis was unsure on how to answer the question. He wasn't a paladin nutjob, or at least as far as he knew considering he didn't know any holy magic, but he was sent by the 'sunshine' guild. He didn't want to scare her off, but didn't want to lie either. He wasn't sure how she came to know the name of the guild, but could only assume it was from the previous adventurers. He takes a deep breath. For now he will refrain from answering the whole question "I am not a paladin nutjob, I don't know any holy magic. Have they been bothering you? Is that why you are running away from me?"
Denny
*The Uzhi still seemed uncomfortable, though didn't look like she was going to sprint away at any second. She straightened up a bit, still looking past him, out the door. The sun was setting.* "I've had this crazy paladin guy chasing me for like a week, so I've been hiding out here. Apparently, I spooked some of the locals and they've been sending guys like you to get in here." *She was quiet for a moment.* "You seem okay, though. How'd you get in here, anyway? And why'd you block up the fountains?"
Julie
"That's unfortunate, can't imagine the stress of having someone chase after you for a week..." Mevis sure hoped the guild didn't send him here to capture this Uzhi. She didn't appear capable of any harm. That being said, appearance could be deceiving. So maybe it would be best to stay on guard? Mevis was conflicted on how what to feel, so he opted to just answer her questions and maybe get some more information. 
"Well, I'm here cus I'm a hero. I was told strange things were happening in the area and someone didn't come back after visiting here. I was hoping to maybe solve the mystery and find the person who was lost. Do you have any idea about that? As for how I got here, I'm not too sure myself. I think when I blocked the fountain it opened the door"
Denny
"Yeah," *The Uzhi snorted in a bitter laugh,* "Strange things." *She pointed to her mouth and raised her upper lip, exposing fangs. She lowered her hand.* "I think that's why that lunatic has been chasing me up and down all of Ramul Ta."
Julie
Mevis wasn't too sure what was the cause for alarm upon seeing her fangs. Were the locals simply not used to seeing races with non-macen traits? This is the Salvain Empire though, known for its diversity. There were Oni with horns, Mogash that were large, Felinid that were basically walking cats, kitsune that were humanoid foxes, and even the elves were a bit odd looking with their pointy ears and some of them even had claws. He wasn't sure if this is what would be considered 'strange ongoings', but for now as a hero he should help this Uzhi.
"I see, it is unfortunate that this paladin is chasing you like this. I see no reason to panic over some fangs. You shouldn't have to suffer like this, hiding in a cave alone fearing for your safety. Have you tried asking for protection? Maybe reporting this man to the local authorities could help also"
Denny
*The Uzhi gave a genuine laugh this time, sitting down in the water.* "You're sweet, kid. I'm a vampire. Vampire Uzhi. First one I've heard of. I used to do nighttime fishing to pay for the replicant blood, but some 'holy crusader' decided I shouldn't get to live in peace. He chased me from way up north, up in Elf territory." *She dragged her finger through the water, no longer looking at Mevis.* "I've been having to kill livestock and wildlife to avoid starving because my coin didn't last me long. I'm sure people think I'm some feral freak whose stalking them, but I'm really just hoping that armorclad pointy-eared fuck gets bored and leaves me alone." *The Uzhi nodded at the door.* "Doubt this spot will work anymore, though."
Julie
A vampire huh? He had merely read legends about them, but after getting involved with the Cult of Adventurr he found out vampirism had spread out across the land. People were still rather accepting of it so long as the vampires stuck to the artificial blood provided. He recalled looking at the page quests that there was a quest to take down a rogue paladin. Perhaps that is the one that has been causing her problem? In either case, what she really needed was to get situated back into society. He hoped the guild could help her, but that would mean telling her that he was sent from the guild. He hoped he had earned enough of her trust, but to be on the safe side he pulls out 5 gold from his pouch.
"Yeah, I don't think this is a good hiding spot anymore either, but even if it was I wouldn't suggest staying here any longer. You are a person who deserves to live a good life. Now, I'm going to confess that I haven't been upright with you this whole time, but I hope you can trust me when I say I want to help you. I am a member of that 'sunshine guild'. I believe they are a good guild, I think they even have a quest to take down this paladin that has been chasing you, but if they don't I'm sure they would be willing to put one. I think they could help you, so I want you to come with me back to guild." He would then hold up the 5 gold in his hand 
"That being said, I understand if you have feelings of mistrust right now and don't want to come with me. But even still, I want to help, so at the very least if you won't come with me take this 5 gold. I know it isn't much in the grand scheme of things, but I hope it will be enough to get you your artificial blood, maybe some bodyguards, and someday safely return back to your home."
Denny
*The Uzhi stood up while Mevis spoke, crossing her arms. Her expression was hard to read, though it was clearly conflicted. Saying nothing, she walked over to the stone coffin and reached in. She pulled out a small pouch that clinked of coin, though very few and drooped it into the pocket of her trousers. Next came an old leatherbound journal that she placed gingerly on the edge of the coffin, not wanting to get it wet. Finally, an arming sword was pulled from the coffin, which she held tightly in both hands.* "You seem really nice," *She said, not facing him,* "But I really don't know if I can trust you. So I'm keeping a hold of this, okay?" *She turned to face him now, looking scared but determined.*
Julie
Mevis sighs. Unfortunate. It was nothing wrong with her, it was all him. He wasn't trustworthy enough. He wasn't like the heroes in the books he read that could win a crowd over with the confident smiles and charming speeches. It was expected that someone as pathetic as him couldn't earn the trust of a single person. He was foolish believe in himself, foolish to think he could be like those heroes. He wasn't strong enough, smart enough, charming enough. Why was someone like him even trying to be a hero?
*Coward*
Mevis shakes his head, trying to clear the voice from his head. 
*Traitor*
Mevis was breathing heavy now. Why now? Why was he so mentally weak? 
*Murderer*
Mevis would flinch and drop the five coins to the ground with his arms shaking. Not now, he was only making things worse! He had to be calm, he was only making things look more suspicious! Recalling the breathing techniques his master taught him he would slow his heart rate down and his arm would stop shaking. He would then get up slowly.
"I... I understand. As I said, I still want to help you, even if you don't want to come with me. I-I'll leave the gold coins on the ground for you. I do hope that you have a better future. I would leave now as my presence here is likely making you uncomfortable, but I just need to confirm that you have no idea about what happened to that one missing adventurer that came here..."
Denny
*The Uzhi gave a said smile, tucking the journal under her left arm while holding her sword in her left hand. She walked to Mevis now, not looking as afraid, though a bit concerned.* "New at this, I guess? I'm going with you; I could use the escort. Keep the gold, you can pay me for recusing me at your guild." *She extended her free hand to him now.* "I'm Juniper. And I sunburn. Do you have a coat I can wear for the trip?"
Julie
New at this? Coming with you? Mevis would look at the Ushi confused. Why was she walking toward him? Escort? It was slowly dawning onto Mevis that the Uzhi was actually going to come with him back to the guild. He couldn't help but smile slightly from relief. Did he do it? Was he actually charming like those heroes in the books? Looking over and seeing the sword in her arms he quickly dispelled the thought. She didn't fully trust him, but was at least willing to follow him. But even still, this was much more than what Mevis was expecting. He wasn't at the level as those heroes, but he felt like he was actually making progress for once.
He would quickly pick up the gold coins in the water and clear his throat. "Uhm... I'm M-Mevis. I will try my utmost to escort you back to the guild. I don't have a coat, b-b-but you can wear my shirt if you want. I also got a ton of rope, but doubt you would like turning into a rope mummy..."
Denny
*Juniper just laughed, pulling at what previously looked like a scarf. She lifted a portion over her head and moved it so it draped down her back. Her cloak covered most of her body now.* "Keep your shirt on. I'd like to travel by night, if we could. Otherwise, we'll have to be really careful. Whichever you think is best." *She reached under her arm and took the small book, handing it to Mevis.* "I don't know the language, but I found it while hiding out here. You can have it."
Julie
Mevis nodded. Heroes shouldn't ever put those they protect in unnecessary danger and he had nightvision so he could make it through the night well enough. "Y-Yeah. Traveling at night would be best." 
He would look at surprise at the small book that Juniper hands at him. He was always fond of books, but seeing how Juniper couldn't understand it Mevis doubted he would be able to either. But it would be rude to refuse a gift. Likely she already knew he wouldn't understand it either but was offering it as a sign of trust. With that in mind Mevis would grab a hold of the book and bow his head 
"T-Thank you. I'll treasure it for the rest of my life" He knew it sounded like an exageration, but it was the truth. He still had that chalice that woman gave him that he saved from the Cult of Adventurr and for as long as he lived he would never lose it. These trinkets to him were a sign of him growing to be a hero, someone that is worthy of receiving gifts. He would look over the book to see if there were any noticeable designs or words that he might recognize. Afterwards he would securely place it in his bag. 
He would then turn to Juniper "So uh, this is just for my curiosity, but you've been here for a while right? Got any idea what this place is? Are there more rooms and puzzles? And what's in the other door?"
Denny
*The book was in common writ, but it did appear to have a cipher. The letters were jumbled and sometimes inverse, with a few symbols being used from other languages. Juniper just looked around at Mevis' question.* "Really only the two rooms." *The only doors here were the two broken wooden ones that ed to the mannequin room.* "Chamber, antechamber, entrance. I'm pretty sure this is a tomb, but something happened before they finished making it. Maybe the guy died." 

*Juniper let out a small chuckle at that, though frowned.* "That was meant to be ironic, not morbid. There's no bones in that coffin, after all, just this sword and that journal. I've been getting in through the tunnels in the pool. They feed into here through the holes in the corner, on the floor." *She pointed them out.* "I don't know why it's all flooded, though, Maybe they made this place wrong. Maybe it was for a Treton. Weird, though." *Juniper went silent, rocking on her heels.*
Julie
Mevis scratched his head. A tomb huh? Well whoever made the tomb took great measures to keep people out. Now Mevis felt kind of bad for breaking it as he suspects the way he got in wasn't exactly the 'right' way. He sure hoped whoever was suppose to lie here didn't mind it being broken into. Mevis would look at the book and let out a sigh but also smirk a bit. Looks like there was one last puzzle after all. He would probably need more than a couple of days decipher it if he was even capable of doing it in the first place. The most likely scenario would be to hand it over to the guild. They should have someone specialized in this sort of stuff. He would then look over to Juniper "Well, it at least provided you shelter for his long. Guess we just wait for night and head out. Sound good to you?"
