The Protectors of Etheria is a stand-alone mod of the game Warlords Battlecry 3 (i.e. it can be run without having the original game installed - 100% free full game). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
