Glowing Sea

Information
The glowing sea is a dangerous place to be in as it houses many different kinds of mutated monsters and creatures. A sea that glows that separates Equestria from the other side.

While its dangerous to anyone due to its high radiation level, its a place that no one would ever want to be with for too long. Though it looks aesthetically beautiful at night as it lights up, its really bad for the health. There are areas within the glowing sea that can't be accessed without certain things.
