Erich was the son of King Urras Greyiron, the first High King of the Iron Islands since the Grey King. After the death of his father, Erich seized his crown and declared himself the new High King of the Iron Islands. However, the priest Galon Whitestaff arose in a fury and declared him an unlawful king, as he had not been selected in a Kingsmoot.
He called all the Ironborn captains and kings to the island of Old Wyk, where Erich was unmade and condemned to death. He avoided this fate by casting the crown into the sea, a sign of his submission to the Drowned God. He was replaced by King Regnar Drumm.
