Objectives
Bring the Vial of Purest Water to Islen Waterseer in the Barrens.
Provided: 
Vial of Purest Water
Description
Islen will have one more task for you before rewarding you with your next totem. The vial of water I've given you is necessary for whatever that task is.
Go now and find her. We shall meet again some day.
Progress
Hello again, adventurer. You're looking well.
What brings you back to me so soon?
Completion
Ah, a vial of water created and blessed by Brine, and gathered by you, no less.
The liquid in this vial will be key in creating a sapta for you, but also used in one other task.
The sapta I create for you should be used to see the water spirits at the shrine in Silverpine Forest, south of the Undercity. The remaining drops, well, the remaining drops I will tell you about if you feel you are ready.
Are you prepared for one more journey, adventurer?
