The Phyrexian invasion of Dominaria is nearing; the Dark Lord's plans are almost complete. Only the Planeswalker Urza stands in his way. Rath's Evincar Volrath has abandoned his post, sparking a brutal contest among his would-be successors. Phyrexia has chosen Crovax to take Volrath's place, bestowing terrible new powers on the bloodthirsty noble. Crovax must still prove his worth, however, before he can claim the position. Meanwhile, Rath's rebels have united in the name of Eladamri, Lord of Leaves, in order to break free of Phyrexia's tyranny once and for all.
