Succubi

The Succcubi, also known as the Wives of Azferon, were Vorgar spirits that entered Tarn during the Worldrending. They resemble female humans, with shapely forms, and great batlike wings. They have tails, which can be smooth, or tipped with barbed spines, and twisted horns sprout from atop their heads. 

Like their master, Azferon, the Succubi seek carnal pleasure unceasingly, and take great delight in seducing those of weaker will than themselves. When their lord was imprisoned in the Lightless Halls, the Succubi were driven mad with grief, and consumed by lust, dispersing into the far reaches of the world, in search for mortal mates. But ever they yearned for the return of their master, who in dark chains was bound beneath the earth.
