There are a number of antagonist options here, being a Night Horrors book, but most of what I really dig into is the clans and bloodlines that one can use to expand upon their own games. There are a number of very specific strange things going on with it that one could form a chronicle around, but don't really fit in many situations (IE - if you're running an ocean-based chronicle, pick this up). Overall, I really enjoyed this much needed drop of blood to rouse me out of the vampire torpor the line's been in without additional content.
