Lucian Gregor Mercus. Dominator of the Dreadnaughts, a Faction of Ursa marines who are dedicated to the Defense of the Ursus Arcadiaum's Homeland.

Tracing his linage all the way back to the ancient Templar families of old "Sir Gregor" is a massively tall 9ft behemoth of a bear with strength and endurance to last for days on end. but despite all that muscle and power he is a Sophisticate, haveign fine tastes in music, art, and women. He was one of the first to answer the call Andarius sent out for unification and stood as a Bastion of Defense alongside his Lord Commander. Sir Gregor revels in showing off his strength and he pushes his dreadnaughts to the utter limits.

Dominator Gregor Lucian Marcus wields the massive Demon Cleaver Axe (once belonging to Ark WolfSteele) and boasts the highest defense of any Uldrin unit. easily able to hold his own even the might Templars of new havens golem power armor and some battle mechs. He can be a true terror to behold.
