In Heroes of Might and Magic III: The Restoration of Erathia, Air Elementals are neutral creatures which can only be purchased in their dwellings in the overland, called Altars of Air. These dwellings are special - they can not be claimed by a team, making Elementals available for anyone to buy freely and prohibiting the use of Portals of Summoning from Dungeon towns. Although Air Elementals look as if they could fly, their movement is actually ground based. This was changed in Heroes IV.
