The Sovereign Pact
Bjorn is the current leader of the biggest Hlaalu tribe in the Idris Archipelago. He took power away from both his older and younger relatives (mostly nephews and nieces) through martial prowess and the backing of the warriors of the tribe. Even though he basically usurped this power after his older brothers death, out of respect for family he honorably exiled family who would not accept his new station. He is distant family to The Sovereign and some of the influential persons in Albion but this connection is often ignored by both sides. Bjorn favors progress for his people through raids and militarily securing some of the best lands. Despite Albion having to deal with many raids lead by those Bjorn commands, he strictly follows the Shinji Code and thus is bloodshed kept to a minimal.
It is widely told that Bjorn is a practitioner of dying berserker arts. He proudly goes shirtless in order to show off his muscles and scars as if to challenge anyone to oppose him. Said to be nearing his mid 40s, the time for him to begin grooming a successor is upon him.
