For stories involving the Eternity Ring as a fixed portal to new Zones, see the Time Zone story arc. The Eternity Ring story arc refers to a series of stories in which Amy Rose and Tekno the Canary travelled through time and space with the help of the Eternity Ring. The culmination of this story arc proved to be the last secondary story of Sonic the Comic, as the comic was immediately turned into 1-part original story, 3-parts reprint.
