Space Vikings

Intro 1017 AD: Vikings have pillaged Lindisfarne, occupied half of Britain, conquered Sicily, founded Novgorod, and discovered America. The free world is on the brink of being overrun by the technologically advanced Norse tribal sailor-warriors. But the greatest terror of the Viking war machine is yet to be unleashed: In great secrecy, they have built a naval outpost on the dark side of the moon, allowing them to strike anywhere on the planet with devastating surprise, then vanish back into lunar orbit with impunity. You are Halfdan the Hairy, and Viking Command has just given you command of your first space longship, the Voidstrider. Shape your crew into a brotherhood worthy of Valhalla, then strike any place of the 11th century CE, with your raiding vessel screaming down from the sky like Thor's Hammer itself!
