Take the Corrupt Moon Well Water to Islen Waterseer in the Barrens.
- Corrupt Moonwell Water (Provided)
Take the corrupt water to the Barrens, <name>. South of Ratchet, hidden along the shore, is an old friend of mine, a shaman named Islen Waterseer. She is a powerful shaman who will help us. Her relationship with the spirits of water has always been strong. Our task being a noble one should be enough to persuade her and the spirits of water to aid us in this task.
You should find her at a small camp right along the water's edge. And, <name>, ignore the pirates... they are but a nuisance and no threat to you.
