In The Company of Vampires
This roleplaying supplement introduces moroi culture, a customizable undead ancestry shaped by vampiric families and curses. It includes alternate racial traits, mixed lineages, humanoid options, favored classes, racial feats, and new spells. A blood noble paragon class offers more than 80 talents for developing a vampire character, while the blood bastard and cambion archetypes allow other classes to take on vampiric traits. Optional hunting rules, a revised vampire template, and guidance for running vampire-focused campaigns are also included.
