Wow, all this interest while I slept. Now look at those questions.

 First of all, any undead being, so yes to all of the ones Soth listed. Necromancy can be included in histories, but actual necromancers cannot live in the appartments...unless they died themselves. So yes, magic is included and can be used, but I'd prefer at least 2 or 3 if there is.Don't want too much magic flying around.

 There will be plots and the such, but most of it will just be the residents interacting with each other. If you guys want to know more, just shoot me some questions.
