The Razor Fields on Mirrodin are named after the "razorgrass" that grow there, plants that appear to be long metallic rods with blade-like edges. They ring like chimes in the winds of the plane.

Leonin have built their capital city, Taj-Nar, in the center of the Razor Fields. The nomadic Auriok wander these plains, trading with those they encounter. Another race populating this area are the loxodons, huge, elephantine humanoids.
