This campaign world is set in the World of Greyhawk campaign setting owned by Wizards of the Coast. Information for the campaign world was compiled either directly from Wizard of the Coast owned publications or indirectly via the Greyhawk wiki.
Additional resources include the D&D 5E resources for the World of Greyhawk assembled by Joe Bloch at Greyhawk Grognard.
Maps of the Flanaess and regions within are based on the original published maps and are custom recreations created by Anna B. Meyer.
