The Plane of TransInfinite Splendor is a magical realm where unicorns enjoy a carefree existence free from the cruelty of man.
In 966 GUE a humble peasant became the first person in recorded history to defeat a Monkey Grinder. He did so by magically banishing the grinder to the Planes of Splendor, where the unicorns presumably kept him in captivity for all eternity.
