A nasty little flint

The flints are a ghastly and malicious race of smilans who are the dominant race on the planetoid, Prixion. They are closely associated with the kristils with whom they occasionally make dirty, strange fire. Actually descended from smilean criminals who were serving sentances on Prixion where the thin atmosphere exposed them to harmful cosmic rays, they seek vengeance on all other smilan peoples and precipitate the Second and Third Great Smilean Wars. Distinguishing characteristics include their height, notably almost 50% larger than normal smilans, their shocks of bright pink hair, crooked noses, and claws on their hands and feet.
