Why “hydromancer” is a great word
HYDROMANCER — [Noun] One who practices hydromancy, the divination of the future by means of water. From Middle English idromauncer, equivalent to hydromancy (from Late Latin hydromantia, from Greek hydro- ("water") + manteia ("divination")) + the agent suffix -er. Unlike "hydromant" (an archaic and shadowy term) or a general "diviner" (who might read entrails or stars), the hydromancer is a specialist of the reflective and the fluid. This is the interpreter of ripples cast by a single stone, the reader of patterns in rain on a dusty window, the listener for prophecy in the drip from a cavern's ceiling. Their craft is the quiet belief that the future, like water, holds no permanent shape, only a succession of revealing forms.
