We know about the following entrances to Castle Greyhawk from various old articles in The Dragon (most notably Joe Fischer's "Hints for D&D Judges" from issue 2), conversations with RJK and EGG, EGG's Gord novels and stories, etc.
Entrances:
- the ruined castle above
- an old dry cistern
- beneath a pool of quicksand
- a simple hole in the ground
- secret stairwell entrance to lower levels (see EGG's "The Hearth of Darkness" short story)
- sewers beneath City Greyhawk (? can't recall where I heard this one)
Exits:
- as above
- gates to Alice levels (via pit and mirror?), Isle of the Ape (via cavern corridor), Chicago/modern world, Greek Mythology area,
- chute to China taken by Robilar
Now, what we know little about is whether or not there were any entrances/exits from Castle Greyhawk to and from El Raja Key? What say you Rob?
