Hundólfr Elkshunner

The tougher Vikings might let Hundólfr Elkshunner on the boat, but generally only when they need ballast. He's not a belligerent person by nature, and not a "berserker", but among the toughest sane Vikings around.

He might grumble a bit at the lack of amenities on board a Viking longboat, but he can handle it. Vikings make fun of him all the time. Not always behind his back, either.

Hundólfr Elkshunner don't have a lot of tact, so it's lucky Vikings never cared much for diplomacy.

His straight forwardness, toughness and sanity makes him a great player for the line of scrimmage.
