Mirrodin is the name of the Magic: The Gathering expert-level block containing the Mirrodin (October 2, 2003, 306 cards), Darksteel (February 6, 2004, 165 cards) and Fifth Dawn (June 4, 2004, 165 cards) expansion sets. The Mirrodin expansion set, as well as the rest of the block, is centered on artifacts and was only the second set to do so (from a card frequency point of view) since Antiquities. The percentage of artifact cards is much higher than in any preceding set. Each of the expansion symbols in the Mirrodin block depicts a legendary artifact: (Mirrodin), (Darksteel) and (Fifth Dawn). Storyline: The world of Mirrodin The setting for Mirrodin is a plane by the same name. An artificial world created by the planeswalker Karn, originally named Argentum, 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 until Glissa Sunseeker became a conduit for its birth. The set focuses on five main regions on Mirrodin, each corresponding to a part of the Magic color pie: The Oxidda Chain, a range of mountains populated by goblins and the human Vulshok tribe. The Tangle, a dense jungle populated by elves, the human Sylvok tribe and beasts. The Mephidross, a mucky swamp, and a home of Nim (zombies) and the human Moriok tribe. Quicksilver Sea, a sea of mercury populated by Vedalken and the human Neurok tribe. Razor Grass Fields, the plains of Mirrodin, overgrown with sharp metallic grass and home to the Leonin, the human Auriok tribe and Loxodon. The main character of the story is the elf Glissa Sunseeker, who visits all these places, guided by revenge against the machines that killed her family. The story is captured in the novel The Moons of Mirrodin by Will McDermott. Magic returned to the setting of Mirrodin with the Scars of Mirrodin block. Darksteel The Darksteel Eye is the second novel in the Mirrodin Cycle by Jess Lebow. It continues the journey of Glissa, after the infiltration of the Synod and the recollection of all the golem Bosh's memories. They now must travel back across Mirrodin to seek the power that resides in the center of Mirrodin. Fifth Dawn The final book in this expansion series is simply named The Fifth Dawn.
