Season 4 Edit
Kalf and Erlendur learn that Bjorn is isolated in the mountains, and they plot to eliminate him, dispatching a "berserker" to carry out the task.
The pair rendezvous with their perspective assassin in the woods outside Hedeby. The Berserker says nothing during the meeting, only offering a menacing grunt in acknowledgement of the terms. Erlendur gives the beserker his father's signet ring, stating that no one will dare hinder him so long as it is in his possession.
The berserker intercepts Bjorn as he is making his return trip from the wilderness. Although initially wounded in the encounter, Bjorn manages to outwit and subdue his opponent. He ties the beserker to a tree and flays his face with fishhooks, demanding to know who sent him. Despite the intense agony, the berserker refuses to talk. Bjorn, frustrated with his lack of cooperation, evicerates the berserker and strews his entrails across the snowy ground.
