Holy Water
“The hydrarastrum of the Pearl-Bright Ocean is indescribable in mortal terms.
“This is not to say that its qualities cannot be imperfectly described: it possesses the glow of liquid light, the milky iridescent gleam of mother-of-pearl, and both the silver-white shine and heavy fluidity of quicksilver. It is simply that such qualities cannot coexist simultaneously in mortal substance.
“This, then, is your warning that when you set sail upon the Pearl-Bright, you are leaving the Realm of Instances for the Realm of Forms, where domain and entity alike are wrought from ideas in conceptual essence, and may thus prepare yourself to be likewise idealized in the course of your voyage.”
