Secret of the Tower is a complete story by Nigel Kitching and Ellie de Ville. Still on the run from Princess Kupacious, Sonic has bumped into Kassim, a thief who convinces Sonic that his lover, Sapphire, is locked in a tall, marble tower. Sonic helps him climb the palace but soon learns that "Sapphire" is a bunch of valuable gems that then turn into a monster guard. The pair escape while they still can, but Sonic isn't prepared to go back a second time.
