Secret of Mana, originally released in Japan as Seiken Densetsu 2, is a 1993 action role-playing game developed and published by Square for the Super Nintendo Entertainment System. It is the sequel to the 1991 game Seiken Densetsu, released in North America as Final Fantasy Adventure and in Europe as Mystic Quest, and it was the first Seiken Densetsu title to be marketed as part of the Mana series rather than the Final Fantasy series. Set in a high fantasy universe, the game follows three heroes as they attempt to prevent an empire from conquering the world with the power of an ancient flying fortress.

The Mana series, known in Japan as Seiken Densetsu , is a high fantasy action role-playing game series created by Koichi Ishii, with development formerly from Square, and is currently owned by Square Enix. The series began in 1991 as Final Fantasy Adventure, a Game Boy handheld side story to Square's flagship franchise Final Fantasy. The Final Fantasy elements were subsequently dropped starting with the second installment, Secret of Mana, in order to become its own series. It has grown to include games of various genres within the fictional world of Mana, with recurring stories involving a world tree, its associated holy sword, and the fight against forces that would steal their power. Several character designs, creatures, and musical themes reappear frequently.
