Succubi
A type of demon, Succubi appear as winged human women with long, spindly fingers, batlike wings, and cat-like eyes. They are lead by the greater demoness Pricina, and function as temptresses who steal the hearts-- and, ultimately, souls-- of the men they seduce.
A succubus can be summoned by void scholars using the Tear of Pricina. If the spell is successful, said succubus will kiss the void scholar's target, draining them of strength.
A description of the summonable succubi is as follows:
A combination of features both horrific and beautiful, this initiate of Pricina hovers before you on spined, batlike wings. The succubus hovers unclothed, her soft curves readily visible. Visible too are her unnaturally long fingers and toes, the digits elongating into piercing claws. The flesh of her hands and feet are black as pitch, a stark contrast to the skin of milky white covering the rest of her body. Where white flesh meets black, the colors spatter into one another as they blend. The skin of her face is pulled tight over her skull, the gaunt appearance contrasting the pleasant softness the rest of her body seems to have. Her eyes also strike you as unnatural, the pupils vertical slits, like a cats. The eyes flash hungrily as they dart, searching.
