So I've been traveling around the blogosphere and this is what I've found.
25 plot seeds for Vampire.
Vampire NPC List Play Aid to help keep it all straight.
A really good summary of the main points of vampire, and some details on another person's vampire adventure rolled into one.
A vitae play aid print out.
Ammunition record sheets.
Good soundtracks for roleplaying.
And using music in Call of Cthulhu.
So there's some additional reading for you.
