Canon:Greyhawk

The first published setting for D&D, created by D&D co-creator Gary Gygax. Greyhawk is Gygax's original campaign, expanded into an official game supplement and greatly expanded upon with many supplements. Greyhawk is the "default" setting for the 3rd Edition ruleset (that is, the rulebooks are written assuming the players are campaigning in the Greyhawk setting) but supplements are no longer actively published.
