Still, there's this...
The Best Laid Plans
Morgan, Tara, Walter and Jean share a house in an unassuming part of town: they keep themselves to themselves and have undemanding jobs that pay the bills. Also, they are not human: Morgan is a banshee, who is drawn towards the dying; Tara is a succubus, who feeds upon male lust; Walter is a djinn, who just can't stop himself from granting wishes; and finally, Jeanette is host to a legion of disembodied spirits who need to be contained lest they inflict great harm upon the world.
It's best for all of them if they have as little contact with the human race as possible, but's what best is not always what's done and compromises must sometimes be made. Tonight, they are all going to get very compromised.
This playset provides the complete resident's book for each of the above four characters, plus suggestions for the mediator to weave this into an appropriate narrative for a one-shot.
