War of the Ring

Prelude
In the Second Age, Sauron forged the One Ring to control the other Rings of Power bore by Elves, Men, and Dwarves. However, he lost the ring when Isildur, first-born son of King Elendil cut off Sauron's forefinger during the Last Alliance of Men and Elves. Later, Gollum stole the One Ring from his cousin Deagol and took it deep within the Mountains. Five hundred years later, he lost the Ring after battling a Goblin. A hobbit like himself, Bilbo Baggins stole the Ring for himself and later ran out, not knowing what the Ring was and thought it was a ring that helped make him invisible.
