The Tower of Druaga
The story of "The Quest of Ki" acts as a prequel to The Tower of Druaga. It occurs shortly after the demon Druaga has stolen the Blue Crystal Rod and taken to a tower originally built by the Sumer Empire, in which the god Anu had destroyed. The goddess Ishtar gives the priestess Ki a golden tiara that enables the power of flight, and sends her to the tower in order to retrieve The Blue Crystal Rod. The game then follows her doomed quest to the top of the tower, with help from the dragon Quox. Upon reaching the 60th floor, Ki reaches the Blue Crystal Rod, however Druaga splits the rod into three pieces and transforms Ki into stone, leading up to the events of The Tower of Druaga.
