It would be nice to have allies with complementary abilities.
@Saarebas Hint, hint, nudge, nudge. Considering one's an umbrakinetic witch doctor who talks to dead people and the other's a necrokinetic afterlife god, they could be friends?? Maybe?? Or, y'know, Lu could play his slinky voodoo master moves on Demetri until the latter figures out what's going on and has a fit and then plots his revenge for ten years. That could work too.
Heck, part of the reason I was asking Katherin about the roommate thing was me wondering if you'd be up for Lu and Demetri rooming together. I like the idea of an afterlife-themed tagteam.
Also, if there was ever situation where a ghost/zombie/other entity were given a command by both of them, and the commands conflicted, who do you think it'd listen to? Would it just short circuit like a robot given a paradox?
