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!
I guess we all know by now what this building purpose will be.
What will the windmil do? Temple of the Winds? Grants resources like in Heroes of Might and Magic?
For this version it will probably just increase the population limit and produce wind and dust elements.
Thank you for working on new buildings/units, I believe that's the last piece we need for pushing the game on an entire new level (new races, more choices for the already existent ones). I like to think at TPC 1.0.0 as what DOTA was for Warcraft 3, I hope we'll reach that disruptive level!
