The metal plane of Mirrodin shines under the light of five suns ... but it's now tarnished by the deadly scourge known as Phyrexia. Besides the Mirran-Phyrexian conflict, the story also revolves around several planeswalkers. Elspeth Tirel (as a new card of the same name, Elspeth Tirel) returns while a new planeswalker by the name of Koth is introduced, a Vulshok native to Mirrodin (appearing as Koth of the Hammer). Venser (appearing as Venser, the Sojourner) and Tezzeret are also involved in the storyline.
