Gravestone is a derelict Mobian town located in the Forbidden Zone on Mobius' surface. It was located within the jurisdiction of the Eggman Empire but remained largely ignored by Dr. Eggman. Most of its inhabitants were Mobians who had not joined the Kingdom of Knothole, hoping to avoid involvement in its war against Eggman. In 3237 Sonic the Hedgehog went to Gravestone after hearing rumors that Tommy Turtle was alive and would be waiting for him there. In reality it was an Infiltrator deployed by Dr. Eggman. Shortly after meeting Sonic and the Infiltrator Tommy were attacked by the robot duplicates of the Destructix, though they were quickly subdued, after which Sonic and the duplicate Tommy left Gravestone to return to Knothole.
