The Grey Tide
Gargantuan ooze, unaligned
The grey that sits on the water from dusk till noon is not weather. It is the living tide itself, come up to look at the town it keeps. It moves without hurrying and takes without reaching, and everything it covers comes back grey and quiet and still slightly damp.
