"Azazel" is the name of a diety worshipped by the drug-cult known as The Timberwolves. Azazel is depicted as an angel in a gasmask, with either two or six wings. Asside from those recurring traits, the specific details of Azazel's appearance tend to differ between depictions.
According to the Timberwolves, Azazel is a fallen angel and the embodyment of all despair in the universe. They claim that it is only through him (and the hallucinogenic drug known as "Bliss") that one can achieve true peace and happiness.
