Under a vile curse, the forest is slowly dying. A few druids, last guardians of this green and endangered kingdom, answer the call of the helpless animals. Save the forest and become its protector! In Nemeton, you have ten moons (ten turns) to explore the forest, create new potions, and summon the spirit of animals to earn as many reputation points as possible. A player's turn has four phases — night, dawn, day, and dusk — then the next player takes their turn. At night, the druid summons the power of the moon to grow sacred plant essences in the forest. The player adds a “Forest” tile to the existing forest on the “Moon” side. Once the tile is placed, the player checks if he can link it in a straight line with another “Forest” tile of the same type (river, clearing, rock or earth), in any direction. The player then places the resources of a certain type on the activated tiles. At dawn, the player turns over the "Forest" tile he just placed on the "Day" side. He can now discover a path leading to a sacred place: an Oak, a spring, or a Nemeton. If it’s the case, the player picks the corresponding "Sacred place" tile in the reserve and adds it to the forest by connecting it to the tile he just added. By day, the player will move the druid to take the proper course of action depending on the "Forest" tiles on which he is walking: gathering all the resources on a simple tile, creating potions with those resources near a Nemeton, or earning the trust of animals. 
 Exploring the forest isn’t easy. When moving forward, a druid can use a power to take winding paths and change directions or enjoy a boost in movements that go in a straight line. However, the player will have to choose between resting and getting back the power to move forward or getting a triskel to earn more points. If he wishes, the druid can use a sacred plant, the archangel plant, to turn into a crow and to fly to any "Oak" tile on the board. He can summon the spirit of an animal to obtain its special powers and then use them during a special move (swap a resource, find a shortcut, etc.) At dusk, if the druid helped to heal the forest by successfully doing virtuous deeds, he puts his token on the accomplished goal, giving him one more resource as well as bonus points at the end of the game if he is the first of the players to do so. Once his turn is over, it‘s the turn of the next player until all players have laid down their 10 "Forest" tiles. Then the players must count their reputation points: Each potion gives the points indicated on the card. The goals show the number of points given. The animals give points depending on the different streaks. Each triskel gives two points. The player with the most reputation points wins the game.
