After Dr. Eggman powers the warp topaz with more energy than it can handle, a wormhole drags him, Sonic, Tails & Amy through it. Now stranded on the Starfall Islands, Sonic has lost his memory and must explore the Islands to get some answers. Accompanying him is a certain green Tenrec who begins questioning her own morals. This is my take on the plot of Sonic Frontiers.
