The Story of Thor (Europe and Japan title; released as Beyond Oasis in US) is an action-adventure video game released in 1994 for the Sega Mega Drive/Genesis console. The player takes the role of Prince Ali, who has discovered a buried gold "armlet" which once belonged to a wizard who waged a long war against the evil wielder of a silver armlet. The silver armlet was used to create chaos and destruction, while the gold armlet had the power to summon four spirits: the water spirit, "Dytto"; the fire spirit, "Efreet"; the shadow spirit, "Shade"; and the plant spirit, "Bow". Ali travels the land of Oasis, gradually acquiring the ability to summon all these spirits, in an attempt to stop the person who has discovered the ancient silver armlet and is once again using it for evil.
