Pale hands reaching out of a swirling cloud of shadow and ethereal luminescence--they are the remnants of a cosmic being, shattered by contact with the madness of mortal men, and left behind by their fellow travelers of the universal void.
Each hand frantically signals a single word in sign language. Driven mad by a desire to be understood--and destined to never be fully comprehended--the Ones Left Behind are plunged into a despair that quickly turns to rage. Rage leads inexorably to the hands pronouncing doom on those who cannot, or refuse, to understand them. Each hand is also capable of creating a baleful magical effect.
