It was only a matter of time... If The Tomeatorium were famous, it would be famous for it's poof chairs. Everyone has to try them at least once. Very comfortable, but very hard to get out of- Though I'll believe Lillith didn't mean to end up in this one.
This idea has been kicking around since I first drew this crossover picture (Here). Dreamkeepers' Lillith might not be the first to end up in one of the people-eating chairs, but everyone does eventually!
