Middle-earth characters
Gollum is an important character in The Hobbit and The Lord of the Rings. Originally he was a river folk (similar to a hobbit) named Sméagol, who found the One Ring after Isildur lost it. Gollum went to live under the Misty Mountains; there he kept the Ring for over 500 years, and in that time the Ring changed him to look less like river folk. He often called the Ring his "precious". Gollum lost the One Ring, which was then found by Bilbo Baggins in The Hobbit.
