Aremag

Aremag was a dragon turtle who lived in the Bay of Chult from at least the late 14 to the late 15 centuries DR. His activities in the bay were well known by the locals of Port Nyanzaru.

Description
Aremag had a blind, milky left eye and was missing a piece of its shell. He had a particularly grouchy personality.

Activities
Aremag considered a region of the Sea of Swords north of Chult his territory. The trade routes from Baldur's Gate and Waterdeep to Chult passed right through it. Unlike other dragon turtles around Chult who simply enjoyed destroying every vessel they encountered, Aremag demanded tribute from any ship he found entering or exiting the Bay of Chult. Ships would toss their treasure into the bay. Aremag then took up the amassed look and stored it in his lair, the location of which was unknown.

Rumors & Legends
In the late 14 century, some believed that the harbormaster of Port Nyanzaru had made an agreement with Aremag, paying a monthly tribute for the beast to keep all other sea monsters out of the Bay.

Background
Aremag is likely named for Gamera, a turtle-like gigantic monster or kaiju of Japanese movies.
