The Northern Watches
The West and East Watches are large castles build at each edge of the abyssal crack cutting deep across northern Rada-Shen. They were initially built there as protection from the beasts that would climb from within but like a volcano, the chasm has been silent for a thousand years and so only a skeleton crew of men man sit watch over the eternal darkness below them. Not even steam rises from the gaping hole anymore, just silence. They say the men that sit the watches slowly go mad, whether from the monotony of watching the darkness each day or from some other evil that seeps into the mind.
