“The brimstone keeps them alive. Like blood, it flows throughout their bodies, keeping their core temperatures high. Unlike blood, they cannot lose a significant amount of it. A few drops at most. It does not regenerate as our blood does. There is a finite amount of brimstone in Yvelia, and every last drop of it is spoken for by the sprites. When they want to procreate, the whole community agrees to donate a small part of themselves. Archer will only live because other members of his pyre have given some of their own brimstone to bring his core temperature back up again.”
