Concerns regarding Underverse & the questline

[Tom Marvolo Riddle]

Coming from the perspective of my characters. Ururu would rather be consigned to oblivion than work for Diablos in any authentic fashion. She was going to risk death and being hunted the rest of her life to escape having to do the things humans do to other humans in her home universe. So I'd probably have to kiss her goodbye until another quest option opened up.

For Tom? He'd want out, he do what he needs to do to get out. Then again he also believes he could eventually consume all of diablo's power if given enough time or at the very least consume a good chunk of the underverse so he can escape under his own power. If that fails, shake hands with Diablo and when he escapes, the person who banished him will wish they were banished instead. Tom will not let them ever go, and he will make them curse their own name and that of their for ever siring them to life. That will only be the start. I imagine every thread would need an M rating.
