Invincibles are the construction of the Mage, a extremely powerful wizard with a taste of conquest. By the time the mage lived, the world was more like a giant chessboard, the players were the wizard using immense armies as pawns. Each of those godlike wizards would create creatures and attempt to steal the supremacy of the land, killing thousand in the process. The mage was among the greatest of those players, but after his defeat against rather nasty creatures, he decided enough was enough and started creating the ultimate warmachines. Thousand of abomination were created under the name of the great game.
