"Thousands of years ago, a Mipedian High Mugess discovered the Khilaian Sphere, an amazing stone with the ability to control minds--a power that, in the wrong hands could be used to control all of Perim. However, when the Fluidmorpher M'ahadil becomes aware of the power of the Khilaian Sphere, he sets out to steal the stone for the M'arrillians. If M'ahadil succeeds, will Perim be able to survive the rise of the M'arrillians?"--back cover.
