Keela is the main villain and final boss from Legacy of the Wizard / Dragon Slayer IV: Drasle Family. A powerful dragon who once menaced the world, Keela was defeated and imprisoned long ago by a great wizard. However, the seal becomes weaker as the years pass by, and Keela would soon break free. In order to defeat Keela once and for all, the Warzen family, descendants of the great wizard, decide to explore the labyrinth where Keela is sealed.

The Warzens carefully explore the labyrinthine dungeon, defeating the various monsters guarding the place and finding the legendary Dragon Slayer sword, which is worn by the son Roas, who unseals Keela and fights him, finally defeating him and putting and end to his menace.
