The Flock is a term for Mortals on whom you can feed without moral consequences. In other words, you can take blood from your Flock and upgrade your own Blood Die one step without having to make a Morality roll.

The new Minor Gift Blood Shepherd raises your Flock die by one step each time it is taken.
The new Level 1 Blood Ritual Shepherd's Call sends out a psychic call that summons your Flock to you. They will arrive in 1d6 minutes or hours, depending on your location, and you can feed from them. However, using them this way automatically reduces the Flock Usage Die by one step after you feed.
Create details about your Flock. What makes them willing to provide you with blood? A higher Flock Usage Die could mean a larger Flock or simply a more enthusiastic or accessible one. The Flock could be a group of insensible drunks, a cult of vampire-worshiping dupes, a handful of prostitutes who don't question a client's proclivities, a supportive loved one who will help however they can or even a couple of farm animals.
