Vikings is getting down and dirty for season 4.

'Vikings' Season 4: Three Intriguing Characters Cast, What Threat Will They Pose To Ragnar?

It's been mere weeks since Ragnar (Travis Fimmel) rose from the dead to take on Paris, and a little illness is not enough to keep the King of Denmark from pushing forward. The cast of the History Channel drama has already taken up arms for season 4 and new photos from set indicate that this will not bode well for their enemies.

"Muddy Hell," Clive Standen (Rollo) captioned his latest snap, showing off a little rain-soaked death and destruction.

In Standen's photo, bodies lie strewn across a dirt road, the lifeless inhabitants of a no desolate encampment. Tough Mudder turned into a killing field.

It's more than likely that these mud spattered bodies are not of Viking descent, but rather the victims of either Ragnar's crew, the French, or the newly cast Finehair. Just because Ragnar's little brother is slated to marry Princess Gisla (Morgane Polanski), that doesn't mean his warrior heritage will fall by the wayside.

Finehair (Peter Franzen), a Scandinavian warrior and King, and his brother Halfdan the Black (Jasper Paakkonen) will become a thorn in Ragnar's side at some point during the fourth season. What they want - and whom they will choose to fight - is currently unknown.
