Once upon a time, a people of great artistry and great knowledge ruled the planet Mekalion: the Kamille. For a thousand years, they prospered peacefully. Then came disaster, when their sun set forever. Facing extinction, the Kamille made the Locus, a device to sustain their minds; and fashioned shape-changing machines, to act out their wishes on the physical plane. Servants they called the Kamelion.
