Sonic and the Lord of the Nazgul is a title within the Sonic the Hedgehog Series, aswell as the third installment of the Story Book Series, following on from Sonic and the Black Knight. Set in the world of the Lord of the Rings, the game combines Sonic's trademark speed with the swordfighting system which first appeared in Sonic and the Black Knight. It is the first appearance of the Babylon Rogues outside of the Sonic Riders games (other than Jet the Hawk who appeared as an unlockable character in the previous game). It is also the first not hand-held game to feature Eggman Nega as a character.
