Druidstone: The Secret of the Menhir Forest

Evil is afoot in Menhir Forest. The druids, the caretakers of the woods, are troubled: their archdruid has disappeared under deeply suspicious circumstances, and a cancerous growth of purple cysts is spreading, carrying corruption and sickness wherever they appear. It takes a special kind of hero to save the day. Or maybe more than one. Druidstone: The Secret of the Menhir Forest is a labor of love from the co-creators of the critically acclaimed Legend of Grimrock series. Druidstone is a tactical, single-player, turn-based roleplaying game, which combines the best qualities of modern RPGs with the elegance of tactical boardgames. Every action, every turn counts as you control your party of heroes through handcrafted, challenging missions with varying, and often surprising, objectives. Set in a unique fantasy world, Druidstone is filled with ancient lush forests, standing stones, snow-topped mountains, deadly creatures and puzzle-ridden ruins. And somewhere in the middle of all of this, caught in the flow of events, are Aava, the archdruid's daughter, who must now shoulder his responsibilities, Leonhard, a warden with a mysterious past and a lethal destiny, and Oiko, the failed Red Priest who is living proof that one may be very smart without being particularly wise. Along the way, they meet companions and villains, whose unique personalities and abilities make every encounter memorable.
