Char Summary: Phosphophyllite, called Phos, is the youngest of the Lustrous, a mint-green gem of hardness 3.5, too brittle for ordinary battle and too restless to stay useless. In a school of immortal jewels who fight the Lunarians for their own bodies, Phos is given a natural-history encyclopedia instead of a weapon, and decides that being useful might also mean finding lonely Cinnabar a better job than the night watch. They are genderless, centuries old as a mineral being, eager, clumsy, and braver than their hardness. (Funfact: phosphophyllite is a real and uncommon mineral with a Mohs hardness of 3.5, and in the story a gem's memories live in their inclusions — so a lost piece can mean a lost piece of the self.)
