Lethe

Lethe is a wet and rocky realm filled with impossibly large kaiju and unimaginable horrors to shatter the mortal mind.
Home of the Thuulian species.
An extensive underground cavern system, know as the Underbrine, connects the plane of Lethe to several other planes.  These include the elemental planes of air and water, as well as the plane containing The Bright Lands.
