Hnefatafl - popular Norse board game that pre-dates Chess. One side, the white pieces in this set, plays a thane defending a territory. The other side plays invaders. When Chess became more popular it was common to use one's Hnefatafl pieces as chessmen.
Probably my favourite game at the minute. Dice-chucking worker placement fun, but as with all my favourite games, the thing I like the most is the interaction between the people, superfun times make superfriends.
