One use only. At the start of the game, after the battlefield has been set up, but before deployment begins, place D3 Citadel Woods on the battlefield. A forest can be placed anywhere at least 1" away from another terrain feature and the edge of the battlefield. Once all forests have been placed, scatter each 2D6". If this scatter causes a forest to end up within 1" (or on top of) other terrain, or within 1" of the battlefield edge, reduce or increase the scatter by the smallest amount necessary to avoid the obstruction. When this has been done, declare which type of forest you want these to be - choose from the types on the Mysterious Forest table. All forests created by the Acorn of Ages must have the same type.
