Hi Gary---
While reading up on some of the gates to other worlds you mentioned in the DMG (Vance's Planet of Adventure, et al), I popped to the sample adventure on a lark, and re-read the following:
The DMG only contains the monastery map, and not the village/wilderness map or the upper works map of the ruined monastery.
Do you recall if the two missing maps were ever drafted and were simply dropped from the DMG for space considerations, or were not completed in time to be published, or what otherwise happened to them? Was this map created specially for the DMG or was it set in Greyhawk or Kalibruhn or elsewhere, back in the day?
The fire opal monastery has always been a favorite of mine. Many many moons ago, I created my own second level of caverns to the dungeons level (at
http://www.greyhawkonline.com/grodog/temp/Ruined_Monastery-Caverns.pdf in case anyone's curious), and I changed the background of the monastery to tie it to the then-as-yet-unpublished T2
I hope the winter's not treating you too badly up there?
