text: Blood is a liquid, usually red, that comes from within a creature’s circulatory system. If the blood isn’t with its previous owner—say it’s in a pool on the floor—the previous owner doesn’t need to be in the art. The blood does need to contextually be blood. Red liquid in a goblet might not be blood. Red liquid in a goblet held by a vampire? Blood. Red anything at a wedding for a pair of ancient vampires? Take a wild guess.
