Arcturian Jewel-Mites
Humanity first came across these gorgeous, horrible pests during the First Glimmer Expedition. Glimmer is an extremely pretty, but only barely human-habitable planet orbiting the red giant star Arcturus, and creatures like the Jewel-Mites are a large reason why the place is only barely habitable. Simply put: Jewel-Mites eat gemstone. One particular type — the kind that’s most hardy offplanet — eats diamond.
