Straif is sulphur, and the kennings call it the strongest of red and the increase of secrets. It is a reagent: the substance that changes what it touches and is never the point itself. Today you are the reagent, or you are in the presence of one. Something is being transformed by contact with something else, and the agent of it will not be the one who takes the credit. Do the transforming and step back. Sulphur is not asked to be the dye.
