Loc for Shael'dryn and Moonwell is 54, 46.

This is the third step in the Raene's Cleansing quest. After finding Teronis' corpse at Lake Falathim and retrieving a gem from one of the murlocs, take the gem to Shael'dryn at the moonwell. The moonwell can be found to the east of astranaar. Follow the main road south out of astranaar (which will then curve and head east) until you come to a dirt path which will head to the south into a small village of foulweald furbolgs. Do NOT take this path south. Instead, turn immediately to the north and run in a straight line (perhaps slightly to the northeast from here). You will eventually come to a small grove type area with a blink dragon. If you see a blink dragon, you are in the right place! Kill this small dragon if you wish, otherwise follow the lamps to Shael'dryn, she will be standing in front of the moonwell. She will give you the next quest in this chain.
