Magnus the Red

Magnus the Red was a giant among primarchs in body and in mind, a scholar-king whose intellect ranged across every discipline the young Imperium had to offer and many it had forbidden. The most powerful psyker of all the Emperor's sons, he saw in the warp not a peril to be shunned but a wellspring of understanding, and he built his Legion and his homeworld of Prospero as monuments to that conviction. His was a tragedy of brilliance, for the very gifts that made him extraordinary also made him certain, and certainty blinded him to the trap closing around him.

When his sorceries revealed Horus's corruption, Magnus defied the Emperor's decree against the psychic arts to hurl a warning across the galaxy, shattering his father's secret labours in the act of trying to save the Imperium. That single desperate choice damned him. Judged a traitor for a loyal deed, he watched the Space Wolves descend upon Prospero and cast down all he had built, and only in that final ruin did he accept the bargain with the Ruinous Powers he had spent his life insisting he could refuse. The Crimson King entered the Heresy not as a schemer hungry for rebellion but as a betrayed idealist, dragged into damnation by his own unbending faith in the power of his mind.
