The setting for Mirrodin is a plane by the same name, an artificial world created by the planeswalker Karn, and named after the Mirari by Memnarch. Mirrodin's environments and inhabitants mix organic and metallic. Mirrodin is orbited by four satellites, which are called suns and moons interchangeably, that correspond to red, black, white and blue magic. Green was notably absent. Glissa Sunseeker, the finest hunter and perhaps the most skilled warrior of the elves, begins her story to find out why the monstrous "levelers" seek to destroy her. It is this search for answers that will begin to uncover the mysteries within Mirrodin.
