Artung Muruk
Artung Muruk was a Greyshield in the Indomitus Crusade, who became a Captain of the Castellans of the Rift Chapter, during its Founding.[1]
However, he became the first Castellan to die, as the Chapter fought Chaos Space Marines in their first battle. Muruk would use his Heavy Bolt Rifle to kill a dozen of the Traitors before he was killed by them. Afterwards, the Captain's rifle was embellished by the Chapter's Techmarines and became a relic of the Castellans, now bearing Muruk's name.[1]
