Brockin was born looking after his twin brother, after their father disowning them. Brockin acts as a sort of older brother to Brookin even though they were both born at the same time. After living years and years in poverty and crime, when a certain crime resulted him and his brother being rich but that soon changed... When an rival of his father who was an bloodthirsty assassin came hunting for the twins. They were soon captured and imprisoned at Freikron's cells for a few years, Freikron  training them to kill so that Freikron could take swift revenge on the father, let the boys kill the father. Then at the point of Freikron's mistake the twins escaped.

They spent years running and dwelling around Dunland and Enedwaith until Freikron captured them again but only one of the twins and that was Brockin. His brother escaped with his life but Brockin was dragged out, facing the evils of Freikron (an uruk-hai). He was poisoned and was nearly killed but was healed then was taken to Angmar, to Carn Dum and was a prisoner of Mordirith. He was a prisoner there for four or five years before Brookin rescued him and bested Mordirith. But Brockin didn't leave Angmar, unscarred. He can still endure some of the pain from his time in Angmar especially the pain of the poison which he can still feel even after years.
