Princess Sally, Knothole Village's first ambassador, is sent on her first mission as an envoy of peace to the rest of Mobius. Sonic and the Freedom Fighters join her on her trek to The Hidden City of the Ancients. Before talks can commence, however, the Ancients ask the FF to help with a small problem they are having: a fire-breathing dragon.
Synopsis: A mysterious echidna appears on the Floating Island. Rather than finding Knuckles, they find a place inhabited by The Dark Legion. Who is this echidna and what does it have to do with Knuckles?
