Gattis Poleimos, son of Targas and grandson of Anorius, finished the Unification War that his grandfather had started decades earlier. Assuming the position of Archon of Umbra following his father's death at the Battle of Serrino, Gattis was immediately tested and suffered initial defeats losing ground and facing civil strife at home because of this.
Rallying his people in their "darkest" hours, he defeated a Coalition Force and began to slowly win back the lost ground and move on to conquer the last few remaining City States. Upon the capitulation of the last of the city states, Gattis proclaimed the formation of the Kingdom of Umbra. Making himself the first King and beginning the Poleimos Dynasty.
