Lore & Background
The tragedy of Magnus culminated during the Burning of Prospero, which occurred before the Battle of Terra. His Legion's obsession with sorcery led them down a path forbidden by the Emperor's edicts on psychic use. To save his sons from the Flesh Change, Magnus made a pact with Tzeentch, a decision that sealed his fate as a traitor. He ascended to daemonhood during the Burning of Prospero, not the Siege of Terra.
In Their Own Story
The winds of Prospero howled across the crystal spires, carrying whispers from a thousand voices that were no longer human. Magnus stood upon the balcony of his tower, his red robes fluttering in the psychic gale. Below, the Legion marched, their eyes glowing with a knowledge they could not control. He reached out with his mind, feeling the cold touch of the Ruinous Powers creeping through the fabric of reality. 'I only wanted to save them,' he whispered to the void, but the stars offered no answer, only the hungry gaze of Tzeentch.
