Ship's Graveyard

Section of the western sea characterized by jagged rocky spikes jutting out (and just below) the water. If that wasn't bad enough, the area is supposedly a common surfacing point of krakens. Found just by the sheer cliffs overlooking the western edge of the Darklit Cities, just by Krakenmount, the rocky formations span most of the southwestern coast.
As a result, shipping in the area never really took off. Who would've thought?
The very borders of the area are often used by pirates as hideouts, as its northern side is relatively close to Northport.

Origins

Not a natural landmark- created by the twin Shrouded ruling over Krakenmount. Nowadays, most believe that it was done to give them some undisturbed space in the water.
However, the uncanny ability for these spikes to tear through hulls isn't purely down to mundane design. In times past, Murmur defeated a great kraken. Part of their success came from dictating the terrain, dragging it through a figurative minefield of sorcery: The Ship's Graveyard. While most of the magics layered on the environment have worn away, some still remains.
