Every battle has casualities, especially, if you are on the losing side. Lucky warriors go to Valhalla, where they will be judged by Odin and have a chance to be part of the great battle.
The unlucky ones go to Fort Ragnarok, the most feared prison of the Viking Age.
Nobody has been back from there to tell the secret of Ragnarok's cells.
Will You be the one breaking the legend? Can you escape from the viking prison?
