In Treeline, the landscape, once lush and green, is covered with cities of stone and brick. The spirits of the forest have awoken and a change is coming!  Take control of your forest clan (the Mushkins, Umbrams, Creeklers, or Stumplings) and reclaim city tiles, restoring the forest and taking control of key tactical positions. The forest will return to its former glory, but will your clan be in a position to lead it?
