Reedmother's Sink

A canopy sinkhole in the reed delta where the reeds drink — a green flooded shaft dropping into a warm underground pool, sacred to the delta-folk and dumping-ground both.

The Siltmouth delta-folk throw offerings down the sink at the solstice, and their troubles year-round. It is their water-shrine and their disposal both — a distinction the Mere Gnasher nesting at the bottom appear not to observe. The village says the sink answers when it has enough to say.
