Xa'sugoth, the Starbrood

The great starborn Xa'sugoth is an amorphous evil entity of madness-inducing proportions that either slumbers on its deathbed or writhes in agony beneath the foul Dernglen, dreaming of breaking through the Plaguelands' great mountains to usher in an age of darkness.
Wounded in antediluvian wars, Xa'sugoth is weak and vulnerable, reliant on those that follow its vision and offer blasphemous sacrifices to prolong its unlife or even strengthen it. Xa'sugoth watches over its followers and rewards them for their unspeakably vile deeds.
Persistent rumours speak of the Grim Gest invoking the avatar of this terrible being into the material world as a last-ditch attempt to secure a loyalist victory over the plains of Hinterlands. It is unclear if the Gest have tapped into the Starbrood's power for their own ends or if they have become its willing pawns in its unknowable plan.

[...] there within the dusky atrium, obscured from the sight of both men and gods, I witnessed a swarthy creature - squat of body and long of limb. As my vision blurred from this antediluvian horror, I stumbled mad and screaming from the 12x12 room that had served as my cell.
