Moriar the Chosen

Moriar the Chosen was once an honoured Captain of the Blood Angels Space Marine Chapter who fell in battle. So great were his deeds that he was honoured by being entombed in a Furioso Dreadnought -- a walking mechanical sarcophagus bristling with powerful weaponry. However, upon entering his new body, he experienced the visions of Primarch Sanguinius during the Horus Heresy and succumbed to the Black Rage, thus becoming the Death Company's only Dreadnought -- an almost unstoppable force in battle.

History
Moriar was once a mighty Captain of the Blood Angels Chapter's 4th Company until he fell on the field of battle at Clamorga defending a ridge against the despicable Eldar. His mortal wounds were too numerous and severe, beyond the skills of the Sanguinary Priests to heal him. And so, Moriar was interned within the adamantium sarcophagus of a mighty Furioso Dreadnought built by Brother Morleo, which had contained the Blood Angel heroes Belaphon, Dario and Amaretto before him. Upon awakening in his new nigh indestructible body, Moriar was overcome by visions of Sanguinius's death during the Horus Heresy. Moriar's own near-death state triggering the Black Rage. Immortal now in his adamantium shell, Moriar managed to survive the ravages of the Black Rage, hungering for battle and death. He was then given the honour of continuing to serve his Chapter by being placed in the infamous Death Company. As the sole Dreadnought of this honoured Company of dead men walking, Moriar fight completely without fear, as befits warriors certain of their own demise, and the furious willpower lent them by the Black Rage. With his Deadnought body he has been rendered nigh impervious to wounds that would kill a regular battle-brother. Some of the Blood Angels' greatest victories have followed in the wake of the furious assaults led by Moriar the Chosen and the vaunted Death Company. Yet despite the glories of Moriar's valorous deeds, a price must be paid, for in the fleeting calm of victory the mighty Dreadnought has succumbed to the effects of the Red Thirst. To restrain him when not in battle the revered Brothers of the Armouriam have modified his armoured suit so that he may partake of the vital liquid.
