Alien Episode: The legendary module Expedition to the Barrier Peaks pulls a masterful Bait-and-Switch on the players by setting up a search for the cave where several monsters that have been terrorizing the countryside have come from, only to turn out that the "cave" is actually a spaceship that has crashed a long time ago and is still functional enough that it can deploy Attack Drone and Sentry Gun countermeasures against the intruding heroes.The world of Greyhawk contains examples of the following tropes:
The Knights of the Silver Dragon (released from 2004 to 2006 by Matt Forbeck) - series of children's books.Greyhawk Classics (released from 1999 to 2002 by numerous authors) - set in the officially released version of Greyhawk, novelizations of seven classic adventure modules.Greyhawk Adventures (released from 1987 to 1989 by Rose Estes) - likely set in the second version of Greyhawk, the time frame listed covers the five novels by Rose Estes.Gord the Rogue (released from 1985 to 1988 by Gary Gygax) - set in the original home campaign version of Greyhawk, which was destroyed in the last novel the first two novels were part of the Greyhawk Adventures series.The Gnome Cache (released in issues 1-3 and 5-7 of Dragon magazine by Garrison Ernst, a possible pseudonym or pen name for Gary Gygax) - set in the original home campaign version of Greyhawk.

A very generic Heroic Fantasy or Swords and Sorcery setting, but one which suits the game's needs perfectly. Ravaged by centuries of warfare, contested by dozens of races and organizations, the Flanaess is crawling with monsters to slay, ruins to loot, and vile magicians to foil. These locations are at the heart of "the Flanaess" - the northeast end of Oerik, the largest continent on the world of Oerth. The setting is named after the great Free City of Greyhawk, a sprawling metropolis of wizards and thieves located next to the legendary dungeon of Castle Greyhawk. Originally developed by co-founder Gary Gygax by amalgamating his and his friends' campaign worlds, it's often thought of as the "default", and has been used to flavor the core edition rulebooks more than once. One of the earliest and most archetypal Dungeons & Dragons settings.
