Final Fantasy Adventure

Seiken Densetsu is a gaiden or spinoff from the main Final Fantasy series.

It was released on the Gameboy as Final Fantasy Adventure. The second game in this series, Secret of Mana was later released on the Super Nintendo. This game was later remade into Sword of Mana, for the Gameboy Advance.

The story follows the hero character, whom must be named by the player, as he tries to save a female character who must also be named. In the journey, our hero ends up discovering that the girl's mother was the last mana tree. The girl will give her life to become the next mana tree, and the boy will be known as the first mana knight.

The game would eventually spawn a series of Seiken Densetu games, which would come to be known in North America as the "Mana" series. The series would still reference Final Fantasy, although it would eventually create its own unique universe.
