If a battleground contains a Glacier, gain plus 1 power to attack or defend for each creature whose heraldry symbol matches that Glacier tile. If, after you were successful in a battle (attack or defense), either player used a matching heraldry symbol for the Glacier space, you may move the Glacier tile to an uncontrolled terrain with either side of the tile facing up. If there are no spaces available remove the Glacier Tile

No control cubes may be placed on a landscape with a Glacier tile. The land is considered controlled as long as the hero remains on that space. Control Cubes may be placed on the landscape immediately after the Glacier has been moved. The controlling hero cannot be substituted for instances where control cubes need to be removed.
