Changes

The Traitor Marines laid waste to their former allies' holdings along the way to [[Terra]]. Throughout the Imperium, rebel and loyal forces battled. Horus and his forces destroyed [[Luna]]'s naval bases, and within 30 days had destroyed the Terran system's defenses. Terra was bombarded and devastated, and eventually, the corrupted Marines landed on Terra, experiencing heavy resistance from the forces defending Terra (among these loyalists were Blood Angels, Imperial Fists and White Scars). The loyalists were outnumbered, and the battle for Terra turned into a siege of the [[Imperial Palace]]. By the 55th day the rebels had reached the walls of the Inner Palace. Horus, who had remained in orbit aboard his battle barge, was at that point warned that the rest of the loyalist Legions were returning to Terra and would arrive in hours. The Ultramarines are were pushing their way to Terra, along with the Space Wolves and the Dark Angels. If this were to happen, Horus' advantage in numbers would be diminished. He let down the force field protecting his battle barge, to lure the Emperor in a final battle that would decide the war.
