Captain of the White Consuls Chapter, Vitrian Messinius is a veteran warrior and one of Guilliman's most trusted advisors. His power fist is an ancient relic of masterful craft and rare potency, gifted to him by the Avenging Son himself for honourable service. Few are as loyal to the Imperial Regent's vision as Messinius – as such, he is responsible for enacting the will of the primarch during the Indomitus Crusade, granted the rank of Lord Lieutenant within the Crusade Fleet and determined to see Guilliman's ambitions through.
