Urdnot Mrax is a young krogan Bastion and is notable for being the first of his kind to join the organization. Though vicious and brutal in battle, he is an idealist by krogan standards and considered a weakling by much of his clan. Because of this, Mrax banished himself from Urdnot and vowed not to return until he proved himself a strong warrior worthy of being in the Urdnot clan.
