Clanbook: Blood Brothers
This sourcebook explores the Blood Brothers, a rare and unsettling vampire bloodline emerging during the Victorian Age. Loyal to the Sabbat and devoted to one another, these vampires exchange blood, thoughts, and limbs, sharing faces, voices, and smiles as they pursue their mysterious purpose. It details the bloodline’s history from 1815 through the end of the nineteenth century, along with its beliefs, powers, motivations, story hooks for Victorian Age chronicles, and a dedicated character sheet.
