The world must be made one again,
A Sega Saturn prequel to the Sega Genesis game Beyond Oasis, Leon fills in the shoes of the protagonist, who was granted the Golden Armlet by his mentor Ordan, to find six elemental beings of spirit in order to have the powers needed to save the country and defeat the Evil Sorcerer Agito along with his army of monsters as part of his destiny to become Oasis's Spirit King.Legend of Oasis provides examples of:
- Astonishingly Appropriate Appearance: Airl looks like a cross between a bird and a cloud, fitting for the Wind Spirit.
- Attack the Tail: The weak spot of the Screamer boss is its tail.
- Chest Monster: In a certain area of the game, the player can find a "seventh" spirit named Tokipin, who is a living chest that can attack with its toothy lid. It passes itself off as the "Spirit of Treasure", but the player can defeat it and, with its dying breath, it admits it was not one of the (canon) six ones and only wanted to help.
- Cumulonemesis: Inverted. Airl is the Wind Spirit, whose body is made of fluffy soft pink clouds, and is one of Leon's allies. She can still hurt enemies with her weather powers.
- Damsel in Distress: A young woman named Myra is targeted by Agito's followers. She eventually becomes brainwashed and has to be rescued.
- Doomed by Canon: Legend of Oasis has two spirits that didn't appear in Beyond Oasis. Naturally, you find out why by the end of the game: Brass becomes an Infinity +1 Sword and Airl changes into a teleport spot that allows Leon to reach the Final Boss.
- Fish People: The boss of the water dungeon is a green Creature of the Black Lagoon-esque man with gills and fins.
- Make Some Noise: Brass is the dragon-like spirit of sound, with the ability to emit sonic waves that can break crystals. He can be summoned from metallic surfaces.
- Numbered Sequels: The European version calls the second game The Story of Thor 2.
- Our Ghosts Are Different: The boss of the dark shrine is a giant cocoon named GhostEgg. After some moments, it opens its many external eyes and absorbs nearby ghosts who keep wailing, until it eclodes to release a snake-like creature named Screamer.
- Prequel: The game is set centuries before Beyond Oasis.
- Shock and Awe: Airl, being the Wind Spirit and with a body made of clouds, can cast lightning as one of her powers.
- Solid Clouds: One of Airl's abilities is to be able to carry Leon on her fluffy cloud body.
- Two Girls to a Team: Dytto's artwork paints her as female. Airl is also referred to as "her" in the opening.
- When Trees Attack: There is the boss named Berbulb, a giant round plant bulb that opens up its folds to release bees at the player.
