Sea of The Devouring Mud-Sand

An Overview
The Sea of The Devouring Mud-Sand, also known as SOTDMS, is a large expanse of muddy clay, sulfuric acid, and quicksand. It is known by its name because of the corrosion effect that it has on organic materials. "SOTDMS" is home to small, crab-like creatures known as Mires, live in this "ocean", because the quicksand, clay, and acid, manage to trap and corrode organisms, this allows them to digest the remains of whoever or whatever stumbled into the sea.

Beyond The Sea
Beyond the "SOTDMS" are four continents, which remain unnamed due to humanity's limited alphabetical variables.

There are rumors of a massive Mire-Queen somewhere in the deep beige sea.
