The Scryer's Dilemma

Since you were so helpful at the mines, would you be willing to help us with a small problem here at the temple? Wise Mari has been complaining recently of a disturbance in his temple. The water elementals have gotten quite playful recently, and made off with his ceremonial staff. If you could help him, I would be most grateful. I may even put in a word with the Jade Serpent for you. Just follow the path to the north.
