The Mask of Secrets

Many Eldar believe the Mask of Secrets to be no more than a dark fable, and perhaps it would be better if this were so. Yet it is very real, kept within a shadowed vault deep within the Black Library. All who look upon this mask see distorted reflections of their own faults and failings, the slightest doubt or regret twisted into a horrific swarm of phantasms that scream and wail as they claw at the psyche of the victim. Those who wear the Mask of Secrets fear nothing while the mask remains upon their face, yet it is said that in the long run they must pay a terrible price for this temporary boon.
