Set in a mythical land of the same name, Hyperborea is a light civilization game for 2 to 6 players that takes 20-25 minutes per player. The game begins at the time when the magic barrier protecting access to the mythical continent of Hyperborea suddenly falls.
The game's main mechanism, which can be described as "bag-building", involves you building a pool of "civilicubes". Each cube represents specializations for your kingdom: war, trade, movement, building, knowledge, growth. Grey cubes represent corruption and waste, and players will acquire them by developing new technologies. (Power corrupts by its own definition, and the more complex a society becomes, the more waste it generates.) Each turn, players draw three random cubes from their bags, then use them to activate knowledge (technologies) they own.
