countains a list of monsters that can be generated in Sheol (possibly not counting the ones *only* generated there)
Should update article, and possibly articles for individual monsters?
EDIT: wood nymphs are no longer generated in Sheol EDIT: list further revised http://sourceforge.net/apps/trac/unnethack/changeset/1113
Adeon has done a great job with Sheol. In keeping with Dante's Inferno, I thought it would be good if it had a further level that led straight to the top. It might consist of a single long narrow (dangerous?) winding corridor, where the length of the corridor is the number of intervening levels. At the end one might need the crystal pick to bust out -- either into a random square of Level 1 or perhaps into the first of the Elemental Planes. The chance to avoid all the usual junk on the way back might get more people going down Sheol. If it went straight to the Planes they would have to think about what they took with them because it would be hard to get back to their stash. Just a thought (dime-a-dozen!).
