Guard Audrey tells you, "We still need to collect more soul gems to craft into the Noble Weapons. You'll need to get a small bit of information from Nuhmudira's cottage located near Uziz on the rim of the A'mun desert. The location is near twenty-one south and twenty-two east by your compass. Apparently something in the book makes you aware of how to use her teleportation device. Once that is complete you can make your way to the island that she found. We have reports that Nuhmudira has moved on and left a student in her place, hopefully she will perform the same deeds as her mentor."
