".....I'm just gonna..."

*A magical video of all the answers Mod did for Dado appears for Xion so Mod doesn't need to repeat herself.* 

"Easier to save time."
Robert
*Dado bows his head slightly.*

"Thanks again so much, Master Mod. I'll be sure to come back if I have any more questions!"

*He smiles gratefully as he gets up, ready to leave.*
Elizabeth
"Huh... Noted... So... Why did my personal magical conduit become the charm for my Keyblade? Is the charm what determines a Keyblade's form and keeps it together or something? Cuz I yoink mine off and poof!" *A small poof of smoke goes off for added effect* "There goes the Keyblade! Or I guess I call it Rainbow Genesis. Also I had it before losing my heart. Which now raises *Another* Question! If a Keyblade is tied to the being themselves rather than the Heart, wouldn't that mean both a person's Nobody and Heartless could summon the same one?"
Robert
"Wait, what's a Nobody?"
Elizabeth
"Me. A being with no Heart. Nobodies and Heartless seem to be two sides of the same coin. Nobodies are the bodies but are heartless and the Heartless are the Hearts but no bodies. It makes no sense to me either." *She says with a look of "Tell me about it..."*
Robert
*Dado cocks his head.* "Confusing nomenclature aside... If the two are connected, what happens to the other if you kill one? Does it also die?"
Elizabeth
"Results not found. Try again later." *She replies cheekily* "Nobody knows nor are they willing to test it out. Not like you can really distinguish most Heartless from one another anyways. For all we know, Nobodies could have the same problem. I just happen to be the only one anyone here knows personally." *Not necessarily true but she's not allowed to say anything more... ~~yet~~*
Robert
"So if Heartless are darkness, would that make Nobodies light since they're counterparts of each other?"

*Dado's eyes shine at the influx of information. Xion's cool as fuck.*
Elizabeth
"You would think but no. While Heartless are Yin, Nobodies are more like the concept of Wu or Mu if you prefer, or nothingness. We are the empty husks. Think of us as just the circls with neither Yin nor Yang. Though that's not exactly the best example considering that's Wuji, or infinity and the perfect being."
Robert
"Huh." *He remembers his fight against the Doll. He remembers Andy's light shining through a hole in its form.*

"Maybe the light gets trapped in the Heartless with the Heart, then. Nothingness, though... That's interesting. How does that work? How do you use light and darkness if you're empty?"
Elizabeth
"They're just elements like Fire, Ice and Air. I don't utilize them as primordial forces. I utilize them as elements. I'm magic student so I've learned how to just use any element. Some things may require you to have a heart to use but most spells don't really need it. Dark Roll and Salvation need one to utilize Darkness and Light as both elements and primordial forces respectively. My personalized spells have no such requirements."
Robert
"So there *Is* A formal magical education..." *Dado ponders this, then considers the advice of Master Mod to learn from his peers. He'll keep them both in mind.*
Duane
"Likely, Xion, if you were to die like this, you would cease to exist. It seems as if your existence as a "Nobody" Was a mistake. Of course I do not see it that way, but your existence is such an anomaly... As to the keyblade, special chains do have the power to change a keyblades shape and strengths. And while we are at it, I'll explain the naming of "Heartless". There was a researcher in Hollow Bastion who studied Heartless in great detail. Pure heartless that didn't have hearts on their own, but appear due to the darkness in peoples hearts. Because they had no heart, he dubbed them "Heartless". Of course some Heartless have hearts now, but this is because..." 

*Mod sighed.* 

"Of him... The researcher became so enraptured by them that he decided to try and replicate them... The specifics aren't there, however his machine that made the heartless made them with hearts, and branded them with a special symbol to differentiate them. An emblem, the one you have been seeing. We call those, Emblem Heartless. Killing those heartless with a keyblade releases those hearts. I admire that researcher and his research, but it had gone too far and has costed too many lives... And he is no where to be found to fix what he has started."
Robert
*Dado listens attentively, then frowns. He goes silent after this explanation.*

"A machine that made Heartless with Hearts..." *The question burns. It eats at all other thoughts. Heartless can take hearts and become Heartless with Hearts. The machine made Heartless with Hearts. The question burns in the air.*

*Dado takes a deep breath, steels his resolve, and asks the question.*

"Did it create new Hearts for the Heartless, or..."

*He lets it hang in the air. Hopefully, he doesn't have to explain.*

*Fuck, the Doll had an Emblem...*
