Lonely Mountain is an adventure game played by 1 to 6 players. Each player controls a group of adventurers attempting to sneak into the Lonely Mountain (Erebor) and steal as much loot as possible. However¸ they must escape before Smaug the Dragon awakens¸ discovers their trespasses¸ and slays them all. The game takes place relatively soon after Smaug attacked and drove out the Dwarves in Third Age 2770. At that time¸ Smaug had not yet sealed all of the minor entrances¸ and he considered the entire inner complex of rooms and tunnels to be his lair. Thus adventurers can enter (and hopefully leave) in a variety of ways. A raid such as the one this game depicts could have been the event that caused Smaug to close all the minor entrances and to gather most of Erebor´s loot into one huge pile.
