"Legacy of the Wizard is a fantasy-themed, action-adventure platform game released for the MSX and Famicom in Japan and for the Nintendo Entertainment System in the United States. The game chronicles the story of the Drasle family's attempt to destroy an ancient, evil dragon named Keela that is magically entrapped in a painting within an underground labyrinth. The only way the Drasle family can accomplish their goal is to use 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, so that they may use the Dragon Slayer to defeat 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. The game itself contains very little text, and does little to add to or even to explain the story of the game.
Legacy of the Wizard is the fourth installment in Falcom's Dragon Slayer series."
