Dreadful Visage

A Dreadful Visage is a Warp entity that can be summoned to assault the foes of the servants of the Chaos God Slaanesh.

History
The sorcerous entity known as the "Dreadful Visage" is said to be a mask that once adorned Slaanesh's own face during the Masquerade of the Palace Grandiose.

On that fell night, the visage took on an evil sentience of its own, and it can be called forth by a sorcerer to bring a measure of its original wearer's horrific aura into the mortal realm.
