Legacy of the Wizard

Dragon Slayer IV: Drasle Family, released outside Japan as Legacy of the Wizard, is a 1987 action role-playing platform video game developed and published by Nihon Falcom for the MSX2. A port for the Nintendo Entertainment System was released in Japan in July 1987 by Namco and internationally in 1989 by Broderbund. It is the fourth installment of the Dragon Slayer series, and one of only five Dragon Slayer games that were localized outside Japan. The game was an early example of an open-world, non-linear action RPG, combining action-RPG gameplay with what would later be called "Metroidvania"-style action-adventure elements.

The game chronicles the story of the Drasle family (an abbreviation for "Dragon Slayer", though the characters are given the last name "Worzen" in the credits) and their attempt to destroy an ancient dragon named Keela that is magically entrapped in a painting within an underground labyrinth. To accomplish this goal, they must find the "Dragon Slayer", a magical sword that is protected by four hidden crowns. The player must use the unique abilities of each member of the family to regain possession of the crowns and destroy the evil Keela. Like many games of its era, the story of Legacy of the Wizard is explained almost entirely in the game's instruction manual.
