The Lost Eye of Ospinode

From the introduction: According to the legend, a long time ago a pirate whose name no one remembers, managed to trick Ospinode god of the seas into losing his left eye in a bet against him. The pirate and his crew fearful of Ospinode's wrath upon learning he was deceived, hid his eye in an abandoned temple to guard it from the passing of time and unwary hands. A few days ago you found the treasure map. It indicates that the temple is on the distant shrimp island. Is it just old hearsay Or does it really exist? Will you manage to recover it without suffering the wrath of Ospinode?
