Investigating the Sea Shrine

Objectives
Investigate the Naga shrine for.
 * Shrine investigated

Description
The naga invaders have set up a series of shrines along the cliffs. I don't know their purpose,, but I believe they're strengthening our foes. I need someone to get in there and root out this threat.

One nearby shrine is lightly defended: Cross the first bridge east of here and then head north towards the bay. You'll find it on a small outcropping. Investigate that shrine and come back with some info I can use.

Completion
The stone in the center of this shrine emits a faint glow and roars with the power of the angry sea.
