I was wondering about the nature of Investiture and liquids. Liquids are solid in Shadesmar, so do they have souls like many of the solid objects? You can soulcast from a liquid, which implies that it does have a soul, but how would things like Lashings work with water. Could a Windrunner lash part of a lake, or would the stormlight just defuse along the whole lake. And how would manifesting liquids work in Shadesmar. We see some of that in Oathbringer, but never the direct manifestation of a liquid. Has Brandon said anything about this?
