Yibb-Tstll

Yibb-Tstll is an obscure Outer God from the works of Lovecraft who has not enjoyed the same level of popularity as it's brethren (Yog-Sothoth and Azathoth). However despite the relative obscurity of the beast Yibb-Tstll enjoys a considerable amount of power and is said to be able to see all things in the universe at all time, making it so wise that only the omnipotent Yog-Sothoth can surpass it in terms of wisdom. Yibb-Tstll's blood is alien and can be utilised as a weapon known as The Black, which takes the form of black snowflakes that stick to a victim and smothers them. Often envisioned as an immobile dark mass of tentacles with a deformed head, detatched eyes and large bat wings under which countless Nightgaunts suckle from innumerable breasts (heavily implying this monstrosity is female). Like many Lovecraftian Horrors the mere sight of this creature can drive humans insane and even thinking too hard on the monstrous being is said to attract its malevolent intent.
