The map to Evenmorn islands, required for the priest's Promotion is located in the tidewater cavern.You have to so up the firest ramp, then out onto the deck, and back down the second set f stairs. After you dispose of all the ghosts and skeletons in there, you will see about five stat barrels.
If you continue towards the back of that room there is another ramp going down to the lowest level, but just before that there is a secret door on your left. if you don't have a character with espert perception, just click along the wall there and it will open.
There are two chests in there and the map is in the right hand chect. Some other low level junk in the left hand chest . . othing important.
