For now, yes. But if we're to assume Assiah and Gehenna are truly gone, then we should consider what we'll do in the future should we spend the rest of our time here. Honestly, I'm not sure what would become of us-- or any demon for that matter, without Gehenna to return to.

[Their world had a fairly specific set-up, after all. The fact that they're still in host bodies implies they still need them to exist here, but-- what will they do if these ones break down? Would they become unable to find new host bodies in conditions like this? Could they actually die instead? 2spoopy.]

...incidentally, did they make you an offer when you woke up? Something in exchange for cooperating?
