"I thought so," Strange simply remarks, as he casts another quick 'don't bother us' cantrip. The feeling of magic lingers in the air like a humid day and Strange just feels more relaxed now than he has before. Now he's willing to speak freely.

"Angels, demons, and the fae aren't from this world originally. They're only trapped here by the Severing. I've been casting some omens to find more about the Severing specifically when I found something interesting: they aren't the only beings from a different world here. I don't have specific people yet, but I do know that some people here, normal people have their souls etched with magic of a different universe entirely."

This isn't the entire truth. The basic gist is right, but the information was obtained from the faerie Nightshade, not Strange himself. And she told him that his soul was wrong as well. Which, that's ridiculous, he's been here all his life, his soul can't be from another universe in the first place. Still, he's selling this with so much confidence and telling Yuya the information in such a matter of fact tone, that it's obvious Strange believes some of what he's saying.

"Perhaps that explains your odd memories."
