The mayor's quest in that game may not be doable for speakup users. Once you find the carpenter the carpenter will be quite mad and will try to kill you and continue trying to kill you as you go for the cavern entrance. If you make it through the cavern entrance alive the carpenter will bless you and leave you some things then disappear. When I foud the carpenter, it was down on the 6th level and though I made it up onto the 5th level I didn't live long enough to make it to the 4th level. You've got to move your character very quickly to survive and you have to move your character very accurately too.
