Thorin Oakenshield
Bilbo Baggins was famously a hobbit, not a dwarf.
There are many books like the Inheritance Cycle (same as 'Eragon Trilogy') but the one I would recommend is The Hobbit/The Lord of the Ring Trilogy. The Hobbit is the prequel to The Lord of the Ring Trilogy.
Thorin Oakenshield became the leader of the expedition in "The Hobbit." He was a dwarf prince seeking to reclaim his kingdom and treasure from the dragon Smaug.

Bilbo Baggins was his name. Thorin Oakenshield was the leader of the dwarves.

The characters Bilbo Baggins, Thorin Oakenshield, Gandalf, Gollum, and Smaug appear in "The Hobbit," a fantasy novel written by J.R.R. Tolkien. The story follows Bilbo Baggins as he embarks on an adventurous journey with a group of dwarves led by Thorin Oakenshield to reclaim their homeland from the dragon Smaug.
Assuming this is a reference to The Hobbit (and if not, be more specific!): They still sang songs of the days of the King under the Mountain, Thorin Oakenshield's grandfather.
The goblins were not able to capture Gandalf, who killed several of them when they tried to grab him.
