Sonic: The Phantom Saga is a fanfiction to be written by MalikTH and published sometime in 2018 on Wattpad and Google Drive. The fanfiction will adapt the games Sonic Mania and Sonic Forces into the Sonic the Hedgehog universe.
While protecting the Master Emerald, Knuckles the Echidna senses an atmospheric disturbance on the island. He investigates and finds a mysterious pink gem near the island's perimeter. He notices that it emits an energy unlike anything he had ever seen, and doesn't recall any ancient stories about it. Thinking that Sonic and Tails might know something about the mysterious gem, he calls the two using a communicator they used during the Death Egg II's launch. However, they don't know, and they offer to fly there using the Tornado and examine it, to which Knuckles agrees.
