Moon-Phase Reagent Vial

Moon-Phase Reagent Vial is a thumb vial of pearly suspension that separates into bright and dark layers as local tidal geometry shifts. A twist of the cap exposes a calibrated grain, enough to align one lunar, menstrual, or cyclical working without hauling an ephemeris into the circle. The reagent is cultured rather than mined, with a faint brine smell and a tendency to clot near gate wakes. One vial holds five doses. Spoiled material turns uniformly gray; using it anyway invites timing errors with the confidence of a clock that has stopped politely. The listed 95 credits covers the item as shown, not bespoke consecration, licensing, or the clerk's suddenly expensive professional concern.
