The Lurians are a humanoid species from the planet, Luria, located in the Ionite Nebula region. Although rarely seen away from their homeworld, some Lurians have moved out into the galaxy to live out their lives.
Although they are humanoid in appearance, the Lurians have developed multiple hearts, four lungs at the minimum, and two stomachs, which has made them a more resistant species against poisons and other multitudes of toxins. The additional stomach also allows them to store liquids for years at a time. They are about the same height as a human, but have a broader and heavier body. They have gray or tan skin with narrow, elongated heads. They also have wide mouths, puggish noses, and small, deep-set eyes. Most Lurians seem to have hair, except for Morn, who has gone bald.
