Mephiston

From Warhammer 40k

Lord Mephiston is the Chief Librarian of the Blood Angels. Then known as Brother Calistarius, he was buried under rubble on Armageddon for seven days and seven nights. During this time the Black Rage came upon him and he fought to surpress it. Calistarius' will stayed strong, however, and he emerged from the rubble as Mephiston, The "Lord Of Death". Under Commander Dante he became the Chief Librarian of the Blood Angles, and his right hand man. He is one of only three known survivors of the Black Rage.

The Reborn Angel

After Gallio and Vode were both killed by Arkio's loyalists, Mephiston decided that he, not Dante, should go and deal with Arkio. He reasoned that since Mephiston was a psyker, he could detect the taint. Touching down on the Blood Angels shrine-world, Sabien, Mephiston found Arkio and searched him for taint, which he found. He was about to challenge Arkio to a duel when Rafen called out and said that he would fight him. Mephiston looked into Rafen's mind and saw that Rafen had seen a vision of Sanguinius and that he was destined to fight Arkio. After Rafen wounded Arkio and Arkio fled, the corrupted Inquisitor Stele ordered the loyalist Blood Angels and the warriors of the Reborn to attack Mephiston and his entourage. By the time Rafen had defeated the princeling daemon Malfallax, Mephiston's iron will had snapped, and he fell into the Black Rage. Rafen directed the power of the Spear of Telesto at Mephiston himself, breaking the curse.
