An Abandoned Keep is one of the seven most basic Encounter Zone types. These are among the easier Encounters (relatively speaking), where the sites themselves have no added functionality. Abandoned Keeps are guarded by Fantastic Creatures of the File:Icon Nature.pngNature Realm in the official game, and either File:Icon Nature.pngNature or File:Icon Chaos.pngChaos in Insecticide or later. Depending on which Plane the Abandoned Keep appears on (i.e. Arcanus or Myrror), it may contain anything up to and including File:Icon Nature.pngGreat Wyrms (or File:Icon Chaos.pngGreat Drakes). Some Abandoned Keeps are empty (containing no monsters).
