Sigefrid

Sigefrid is a Danish warlord, one of two fierce brothers carving out power in a fractured England. Ambitious, volatile and hungry for conquest, he schemes with allies and rivals alike, always angling for more territory and glory. He rules through fear and force, quick to charm and quicker to threaten.

Björn Bengtsson gives Sigefrid a live-wire unpredictability — you never quite know if he's about to laugh, negotiate, or kill someone. The writing makes him a genuine wildcard among the show's Viking factions, and Bengtsson leans into that volatility with a physical swagger that makes every scene he's in feel faintly dangerous.
