A shimmering cerulean mass the size of a tall human seated on a low stone, its outer surface like wet silk that refracts light in faint bands. Two enormous, opaline eyes float near the top of the mass, each rimmed with a halo of tiny reflective granules that glitter when focused. No mouth, nose, ears, or other facial features are visible. Its surface constantly ripples with slow, thoughtful pulses. When it moves it slides with surprising grace, leaving thin, pearlescent streaks on stone. Contradictorily it sometimes sprouts crystalline shards that chime softly when it thinks hard, an odd, fragile ornamentation for a creature whose body is otherwise entirely fluid.
