You don't have to apologize. Curiosity has always been one of my favorite traits in humans. As unpleasant a story as it is, there is a part of me that's happy to be telling it to you now.

[Even though he doesn't look it. But it's a demon's happiness -- the sort that would be difficult to explain without simply having to use a different word all together.]

But I'm afraid this is only the introduction. The real cause of the rift between Lucifer and myself is what became of it all in the end.

As I've mentioned before-- Lucifer and my other siblings are special as far as demons go. We're born from the concepts from which we're derived and have always existed, long before we first incarnated. As the incarnation of light itself, Lucifer is considered the most powerful demon in Gehenna... but there is still one demon more powerful than him. A demon born from the consciousness of Gehenna itself.

And because of our research... that demon was able to incarnate in Assiah for the first time in history.

[There's really only one entity he could be talking about here.]
