Bilbo Baggins finds himself lost in the dark tunnels under the Misty Mountains after becoming separated from the dwarves. He comes upon Gollum and the two engage in a riddle game, with Bilbo wagering his life against Gollum's ring should he lose. Bilbo wins the game of riddles and escapes with Gollum's ring, unbeknownst to him that it is in fact the One Ring of power that could rule them all.
