"Welcome adventurers! The sight you see before you is The Astrolabe!"
Indeed it is and this is the highest part of The Severed Hand one can reach and also where one can find Larrel and his assistant Gelarith, the latter who is looking for the missing parts to the Astrolabe Now if you've come to this part without the help of the rest of this chapter, you will need all the missing parts to the Astrolabe before Larrel will converse with you. Restructuring the Astrolabe will retain some of Larrel's sanity and he will be able to converse with you then rather than his mindless dribble.
Are you missing some or all parts of The Astrolabe? Tsk, tsk, tsk. You haven't been exploring very much now have you brave warrior? Well then, off you go to continue thy search or simply go here for the answers.
Once you have recovered the missing parts to the Astrolabe that Gelarith needs, he will put the Astrolabe back in working order and Larrel will be able to be understood as well as talked to, which I suggest you do. If you've picked up the DIARY OF EVAYNE hand it over to Larrel for it was his daughters before the tower fell. Larrel will unleash the power of the Heartstone Gem and will give you a vision of where you are to go next in your quest for the evil that plagues Kuldahar.
Return to Kuldahar if you must to rest, identify or sell items as well as get your reward and item from Orrick The Gray.
