Conquest of Elysium 3 is an old school fantasy strategy game. You explore your surroundings conquer locations that provides the resources you need. Resources needed vary much depending on what character you are, e.g. the high priestess need places where she can gather human sacrifices, the baron needs places where tax can be collected and where iron can be mined. These resources can then be used for magic rituals and troop recruitments. The main differentiator for this game is the amount of features and special abilities that can be used. The game can be played on Windows, Linux (x86 and raspberry pi) and Mac OSX (intel and powerpc).
The Troll King's mother is capable of scrying and of making the forests come alive. Forests that have been turned alive by the troll mum will reanimate any animals or humanoids that dies within it. The forests will also get shadow trees or magic fungus that will attack those foolish enough to enter. Most animated plants are stealthy within the forest and cannot be seen by normal troops.
