The Hero of Helsreach, as Grimaldus is known, is a spiritual icon for his fellow Space Marines, epitomising the selfless endurance they all aspire to. When Helsreach Hive on Armageddon was overrun by Orks, the High Chaplain held the line until the walls and roof came crashing down around him. Believed dead for days, he dragged himself free from the rubble carrying three divine relics, which his Cenobyte Servitor retinue now carry with him into battle.
