Here is my sheet, at last.

[i]Moggotheddon, Slave to the Chains[/i] - once a titanic Keeper with the strength to crush mountains, now he is the embodiment and defeat and helplessness. After his fall from power he was banished to Tartarus, shackled deep within in the depths of the bottomless pit and tortured by the horrors within. However, his jailers drove his primitive mind into unspeakable rage. Through sheer willpower he broke his chains and climbed out of the pit. The last vestiges of his former intelligence still remembered the way out of the Underworld, and so by pure instinct the Keeper crawled until he emerged from the Underworld, into a deep cavern below Cyprus. There, he collapsed from exhaustion.

His colossal form is hideously mutilated; impaled and sliced in a thousand places, his entire body bathed by fire. His ears and nose essentially melted away and fused with the rest of his grotesque visage, while the rest of his form bears the scars of defeat and endless suffering. His wounds, kept fresh by the sickly powers of Tartarus, still ooze blood. However, despite all of this his mangled form remains puissant.

Tormented to the point of insanity, the Keeper is no longer lucid. More akin to a raging and terrified beast, he exhibits no strategy or true aggression of his own; prone to only the occasional fit of anger in which his wrath usually inflicts more harm on any followers he accumulates than on enemies. His broken manacles are living things of their own, writhing like snakes and constantly fighting to subdue Moggotheddon once again. The behemoth alternates between long periods of peaceful slumber when he controls the chains, and nightmarish time spent awake, forfeiting his mind to the unadulterated rage that is his only way of overcoming the power of his chains.

Expect an OP soon; I think I've figured out what I'm going to do.
