When the gates to the Abyss swing wide, the first demons through are often vrocks, vulture-headed scions of rage who wheel through the air on black wings or dance with the exultation of their fiendish power. Their hatred for mortals is matched only by their desire to inflict suffering through their horrible screech or their devastating dance. Vrocks form from the souls of hateful mortals who are thus given another chance to inflict their rage on the world.
