As the dust begins to settle and the clouds spread wide to reveal a late morning sun, Headmistress Vendira Silverpatch opens the front doors of the famed Pumpernickel Academy wide enough to provide sufficient visibility to the rest of the grounds ahead. Content there are no more students caught in the remnants of the latest storm, she extends her right hand, palm facing upwards, out into the air before her and, feeling no precipitation, the gnomish administrator gently nods her head in a pleased manner, cracking a slight smile before turning to her aide, “Gertha, would you please be so kind as to collect the children and prepare for a Gratitude Ceremony?”

The diminutive assistant, a stout halfling having spent her formative years walking these same hallowed halls, nods enthusiastically, reaches into the burlap satchel that hangs at her side to procure a pen and paper, then proceeds to catalog every student in every class in every hallway, one-by-one-by-one until all are present and accounted for, then leads them into the main hall to prepare the ceremony.

While her associate busies herself with preparations, the headmistress strolls out onto the academy grounds and surveys the surrounding domain. “Splendid, splendid indeed,” she remarks to no one in particular. “It seems Moldren has been well-advised.”

Standing just on the edge of the grounds, one of the unknown saviors sits down to collect his breath after singlehandedly saving over a dozen children from stray lightning strikes. The headmistress calls out to him invitingly, “Welcome to Niatha my friend, thank you for your service! Please do come in out of the weather to our lovely academy, you and your friends are welcome to wait with us here until Adviser Moldren arrives. We can give you sustenance and rest to heal.”

 “Ooh, and he needs a lot of BOTH,”  she thinks to herself.  “Look at all those lightning burns!” 

Without waiting for a response from the stranger, the headmistress draws a sending stone from her purse and reaches out to the adviser directly, “Well chosen Moldren my friend. Not only did they minimize structural damage, they saved our future as well. Gratitude Ceremony to commence in their honor.”

Moments later, the stone chimes the adviser’s response, “Excellent news my friend. I shall bring the bells, see you shortly.”

Thalin pats Arkatos gently on the shoulder in an unburned spot, he speaks in Elven,   ”Let us go inside, brother.  They will take care of those burns and perhaps have something decent to eat as well.”

"  Are you guys okay?, Looks like you took most of the beating...  " Astrid said to her elf brothers as she walked past towards the rest area. "  I'm starving, I will eat all the buffet if you guys don't hurry up...  ", she held her belly with both hands.
Lioslaith
  ”Nothing a good meal, rest and pocket full of coin won’t fix.”

 I too am hungry and tired, how long to the ceremony,  and how long is the ceremony? 
He looks at his brother and his extended family. He looked at his clothes,  brushing dirt off and trying to straighten them as best as possible.
Lioslaith
Thalin helps his twin dust off, fixing the set of the clothing out of habit.   ”Meh, who cares. They’ve promised food and healing.  That will suffice for now.”  
bluecrackpot
Eager to stay on schedule, the headmistress saunters back towards the main entrance, turning her head briefly back towards the group once she alights on the front steps, “Please forgive my haste, it is almost time for our midday meal and I need to make preparations for visitors. I will send my assistant Gertha to guide you to the main hall shortly.”

Once more not awaiting a response, she rushes inside. Unbeknownst to her — but not missed by the 4 pairs of keen elven eyes peering in her direction — a shadowy figure around her height slips in behind her from the northern side of the building before the doors close.

There are a few felled oaks strewn along the grass between the siblings and the entrance, along with a few patches of lightning-singed soil, but no immediate damage to the stone walls or glass windows of the venerable construction.
Wrexham
  Brothers, did you see that?A shadowy figure just slipped in.   Dusk says as he starts to move that direction.
Lioslaith
A brief nod and the drawing of his swords are all that is seen before Thalin touches his twin on the shoulder and they both disappear in a blink, dimension dooring inside to intercept the shadowy figure following the head mistress…
bluecrackpot
Before Astrid or Arkatos can react, the twins vanish from the grounds and reappear directly inside the entrance to the academy, sturdy metal door closing shut behind them as their bodies materialize into a magnificently lit corridor of marble floors and walls lined with what appear to be pedestals propping up solid gold busts of various female gnomes, presumably past headmistresses of the academy. Though the headmistress is oblivious to anyone else’s arrival in the entranceway as she bustles down the hall in a dead sprint, the twins hear a faint hissing sound emanating from behind several of the busts on the lefthand side of the corridor.
Wrexham
Dusk quickly draws his dagger out of his sheath and turns towards the hissing sound.
bluecrackpot
As Dusk draws his weapon, the light from above reflects off both his blade and the two his brother wields, piercing the darkness where the hissing emanates from to reveal an otherwise normal gnomish youth save for two red glowing eyes. Once revealed, the shadowy figure ceases making sound.

"  Let's go Arky!

With the shadowy figure revealed and the party's weapons drawn, it is time for action.

First up, Thalin recognizes the shadowy spaces behind the pillars make for decent hiding spots for small humanoids such as the shadowy figure. Upon closer inspection, he also notices that the pillars themselves have the faintest of burnt orange glyphs just underneath the busts themselves, indicating the statues are magical in nature, though what they are or how they operate is currently unclear. Given there appears to be some sort of switch on the wall within the shadowy figure's reach...

Outracing lighting bolts was  not  a fun experience.

Sure, Arkatos was quite capable of doing so, thanks to his patron’s gifts. Something that most people were absolutely incapable of. But even so, he wasn’t  always  successful, and as the most mobile and agile of his brothers, he ended up taking the brunt of lightning bolts where he had to use his body as a shield, rather than getting the kids out to safety right away. Now sure, some might argue that acting like this, damaging his body simply for some kids, even those at an academy, was a waste. That Arkatos and his brothers, with the skills and abilities they were famous for, had much better things to do with their time and skills. And to some degree, they weren’t  wrong  either...

Akatos just didn’t think that saving lives was ever a waste of time or resources.

Of course, Arkatos isn’t the only one that can leap through space. Just the most proficient at it. Or at least, Arkatos saw himself as the superior teleporter, but he couldn’t actually teleport the furthest. Instead, the others had a more powerful spell that allowed them to take another with them but came at the cost of a sharp delay in actions they could take afterwards. Those handful of seconds could make a huge difference in a combat situation. Like the one they were being yanked into immediately. Because of  course  they would have no time to rest after the storm. Fortunately, he still had his trusty Quarterstaff out, so he didn’t even need to summon it as they dived into the fight.

Though what the threat turned out to be was... worrying.   “Non-lethal only,”   Arkatos said with narrowed eyes, catching a glimpse of the skulking child and its red eyes. Until they got to the bottom of this, no one would be dying here.

In his haste, Thalin triggers the academy’s entranceway defenses on the way to his quarry, flames of fire bursting forth from each statue, engulfing all but the spaces between and behind the pillars. Luckily for him, his keen eyes had spotted the danger beforehand, mitigating some of the damage. Once in melee with the shadowy figure, Thalin’s mystical mark melds into the figure’s forehead as his short swords slash at its body. One strike in particular is more dreadful than the rest, and once it lands, a loud shriek is heard, though not from the shadowy figure.

Somewhere down the hall, a young red-headed gnomish girl begins running to the glass door that slides down from the ceiling, enclosing the combatants in the entranceway. The girl pounds her tiny fists against the door, screaming, “Frederick!” as the shadowy figure prepares to cast a spell, seemingly oblivious to her presence and voice.

Though within Astrid and Arkatos’s counterspell range, sight of the shadowy figure is obscured by the shadows, the pillars, and their brother in its face, negating its usability. Two swift blasts of toxic fire repel Thalin 20’ back, now in line with the second pillar closest to the entrance as the shadowy figure steps out of the shadows and behind the pillar out of sight of all save the girl to cast another spell, the result of which is met by a gasp from the youth outside the glass as the shadowy figure vanishes from sight.

 
 Spoiler: OOC 
I misspoke regarding the DEX saves before; they are not save-or-suck. A successful save still takes half damage (i.e., 16 fire damage) unless otherwise mitigated by resistance or some other effect/ability, and a failed save takes the full 32 fire damage.

The shadowy figure’s two toxic fire blasts deal a total of 23 fire damage and 9 poison damage to Thalin as he is hellishly blasted backwards. Below is the current situation,  Dusk is up !

 Spoiler: Casting spirit guardian  
You call forth spirits to protect you. They flit around you to a distance of 15 feet for the duration. If you are good or neutral, their spectral form appears angelic or fey (your choice). If you are evil, they appear fiendish.

When you cast this spell, you can designate any number of creatures you can see to be unaffected by it. An affected creature's speed is halved in the area, and when the creature enters the area for the first time on a turn or starts its turn there, it must make a Wisdom saving throw. On a failed save, the creature takes 3d8 radiant damage (if you are good or neutral) or 3d8 necrotic damage (if you are evil). On a successful save, the creature takes half as much damage.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.  (3d8)[ 12 ]  bonus action turn boots of speed on. Move up 30 ' and then use 90 feet to sweep back and forthuntil he ends his turn next to where the enemywas.
 

Dusk casts spirit guardian  and moves towards the area where the devil spawn was last seen.

Though surprised by the flames, Dusk recovers well enough to execute his go-to opening move, clicking his heels together to activate a speed boost and summoning his spirit guardians, myriad tiny fey creatures that hover in a 15’ emanation around him as he saunters into the middle of the room before zooming around the entire closed space, ensuring the spectral beings pass through every open space seeking the shadowy figure before Dusk ends up in the corner where it was first spotted.

“What are you doing to Frederick?!” the little girl screams. “Please stop hurting him!” she implores.

  “WHAT PART OF ****ING NON-LETHAL DO YOU IDIOTS NOT UNDERSTAND?!”   Arkatos’ voice thundered through the now-sealed chamber as his face twisted in disgust at his siblings' actions. They were fighting a ****ing  kid , what the **** were they doing acting like it was a big dangerous enemy?! Okay, sure, the academy’s defences and the flames were annoying, Arkatos managing to dart aside so the pillars only brushed against him instead of adding  more  burns. But that was their own stupid fault, and the actions of his siblings were beyond acceptable.

Marching up to Dusk Arkatos grabbed his shoulder and told him with a growl.   “Drop the ****ing Spirit Guardians or I’ll drop it for you!”   He ordered, despite all the spells he had used protecting others, he still had a  Dispel Magic  up and ready to go. And if that didn’t work? Well, let's see how well Dusk kept up concentration of the spell while Arkatos was punching the stupid idiot in the fact!

As Thalin scans the room for signs of the shadowy figure, two gnomes rise up from beneath the floor just outside of the webbing, accompanied by a jet black fiery dog of some sort, and, simultaneously with their arrivals, a fourth demonic-looking being emerges in the shadows along the far wall.

The first of the gnomes, a middle-aged man with brown spectacles, skirts the edge of the webbing and walks towards Dusk and Arkatos, careful to avoid the tiny fey flitting about. As the gnome approaches, Dusk hears in his mind, “Welcome, dear friend. What brings you here with such protection?” as the man gestures towards the spirit guardians. “It is unnecessary in this place.”

The other gnome, a slightly younger-looking woman wearing a blue beaded necklace follows suit, speaking to Arkatos in his mind, “My my my, how troublesome it must be to keep those two in check, dear friend,” indicating the twins. “I may be able to help with that, if you’ll let me.”

Meanwhile, the unusual canine briefly sniffs the air, sensing the flames from the statues, takes a quick look at the only empty corner, growls, then races across the room towards Thalin, viciously sinking its teeth into his leg, drawing blood and cauterizing the wound at the same time.

Sensing something in the empty corner based on the dog’s initial reaction, the winged demon in the shadows flutters in that direction and looks out into the room in an attempt to pierce the light. Momentarily dazzled by the brightness, it shrieks as if blinded and attempts to disappear into the shadows, a defensive maneuver that would ordinarily suffice against common folk, though not against the keen elven senses in the room.

Woohoo, 4 new “friends” have showed up to the party … and the shadowy figure is … somewhere?

As if summoned, the headmistress appears next to the girl, puts an arm around her shoulder, and attempts to calm her down, “Now there young Trixie, you know it isn’t safe for you here, please go back and join your classmates.”

Trixie refuses to cooperate, screaming, “They’re hurting Frederick! And why are my parents here?!”

The headmistress turns to follow the young girl’s gaze as Thalin takes a swing at the female gnome after absolutely shredding the hell hound to pieces, “Oh my, those are not your parents young one. That team of fou—,” she hesitates.

 “Oh my, the woman is a rogue,”  the headmistress thinks to herself, a slight smile crossing her face as the shadow demon swoops out of the corner in search of a better hiding space before shattering to pieces with a loud BOOM.

As the female gnome leans over to give Arkatos a … kiss?! … the male gnome disappears from sight. In Arkatos’s weakened state, the unexpected affection drains him of his last drops of energy, causing him to slump to the floor, motionless.

 
 Spoiler: OOC 
Both the hell hound and shadow demon are dead. The male gnome is not in sight, and Arkatos is down with max hp reduced by 20 unless someone has a reaction that can help him.

If there are no reactions forthcoming and there are no questions for me, allow me to wish you a Happy New Year (belatedly if it’s already past midnight for you)!

Dusk runs up to the female gnome and lashes out three times with his dagger and three times with his fist, the swirling fey still helping him as they hurt the female gnome.

Even though Arkatos spoke harshly to him moments before, Dusk dashes in to avenge his brother, slashing the female gnome until she drops to a knee before finishing her off with his fist. As she crumbles to the ground, her form changes to reveal a scantily-clad winged fiend that looks nothing like Trixie’s mother.

 
 Spoiler: OOC 
3 out of the 4 beings that appeared in Round 2 are down, with the 4th somewhere unseen, and still no sign of the original shadowy figure.

 
 Spoiler: Astrid Only 
If you want to look for the shadowy figure, do a Perception check in OOC. If you want to understand what's going on with the male gnome, do an Arcana check in OOC. You can do one or the other on your turn as a Search (Perception) or Study (Arcana) action unless you have a feature to do both types of Action on the same turn. I didn't look at your sheet closely enough to see if you do, so please let me know if it's possible. Or do something completely different, whatever you want. 🙂

Astrid understands the male gnome is gone, and approaches to Arkantos and with a gesture a war light covers him, "  It seems that the other gnome ran away to ethereal plane  "
