deep trench

an area off limits to most.

the ocean floor is littered with nooks and crannies, caves and air pockets, there's also the trenches. oh, the trenches.

some are shallow and house rare creatures. some are a little deeper, and it's where some of the more secret operations are carried out. some are so deep, so dark, that you may never find the bottom; it's in these trenches where you look into the darkness, and the darkness looks back.
