Aerdy properly refers to the now-defunct Kingdom of Aerdy in the World of Greyhawk campaign setting. Sometimes "Aerdy" is used in reference to the Oeridian tribe which founded the kingdom, though the proper term for the tribe is "Aerdi" (which is also the adjectival form). "Aerdy" can also be used in reference to the Great Kingdom of Aerdy, the imperial successor state of the Kingdom of Aerdy.
