The Company of Light and Shadow
The Black Rift
The Black Rift is a deep canyon set directly in the Shadow Swamp. On all sides, swamp water flows or trickles into the canyon, falling over 100 feet to splash in the waters below. Despite the constant influx of dark fluids, the water at the bottom of the Black Rift never rises and the swamp never drains- a peculiarity of the Plane of Shadow.
The Black Rift is more morphic than the rest of the plane. Its overall shape remains more or less stable, but small-scale terrain are common, and the interplay between Weave and Shadow Weave is more malleable.
Beyond its many layers and plateaus, deep in the center of it, the dark leader of the Sharrans Despayr works his way to create a terrible tear in the Weave.
