Tales of Destiny is a follow-up to Tales of Phantasia. Like its predecessor, it has the structure of traditional Japanese role-playing games, but substitutes turn-based combat for action-oriented one. Battles take place on separate side-scrolling screens and resemble those of a fighting game. The player controls the main hero, navigating him on the battle screen and performing various attacks and combos. Other party members are controlled by the game's AI, but it is possible to pause the battle at any time and assign new combat style to any one of them.
In the past, a comet crashed into the world, throwing dust clouds into the sky and shrouding the world in cold and darkness. At about the same time, the inhabitants, the Aethers, discovered a new form of energy from the meteorite's core, which they named Lens. Combining this with further research, the people were able to create cities in the sky and live in them. Unfortunately, only a select few were chosen, leaving the rest of the people to remain on the bleak surface of the planet. These people became known as the Erthers.
The story of the game begins when country-boy-turned-adventurer Stahn Aileron, who seeks fame and adventure, sneaks aboard the flying ship Draconis as a stowaway. He is found out by the crew and forced to work as a deckhand, but when a large hostile force attacks the ship, the crew is overwhelmed and Stahn breaks free during the ensuing chaos. Looking for a usable weapon to fend off the attackers, he gains access to a storeroom and discovers a "junk" sword. However, the sword starts talking to him, calling itself Dymlos and claiming to be a sentient Swordian from the Aeth'er Wars. Armed with Dymlos, Stahn fights his way to an escape pod, which he uses to escape the rapidly descending ship before it crashes into the ground.
