The Lutrillians were sentient humanoids indigenous to the planet Lutrillia, in the Yarith sector of the Outer Rim Territories. Members of the species had broad, wrinkled features, pointed ears, and hair growing from their heads and cheeks. Thick skin and a layer of blubber bolstered them against physical damage and harsh cold. The Lutrillians evolved a nomadic lifestyle to avoid subterranean predators and to visit oases scattered about their remarkably flat homeworld. They adapted to the introduction of galactic technology by moving into wheeled platform-cities. These mechanical beasts lumbered across the planet's equator, stripping the surface of food, water, and raw materials. Lutrillians enjoyed adventure, high stakes, and chance-taking, traits that made them natural entrepreneurs.
