The Sweet Delight
Imagine a world of crushing darkness in all directions. Below your feet is a deck and beneath that endless water in all directions. Nightmarish aberrations beyond that defy description often lay just beneath the surface. The weeks of unending darkness between ports driving men to madness. Ports filled with cutthroats and ruled by men made monsters more often than not.
A place where any sea tale you hear is real more of than not.
This is the Undersea.
