Song of the Deep Sea

Exploration Stage: Moonshore Restaurant
From: Martha
Description: The seal protecting the source of Moonshore's subterranean magic is quite powerful. Much nastier than I expected. I also found a kalimba in my vision that produces multiple tones. Look for it near the water.
Completed: Your eyes are sharper than a medium's! This is the kalimba I saw in my vision. It's like she's playing the song of the eternal abyss, making it impossible to find what is hidden. It must be a treasure that some mage holds dear.
