The Losonta are human-sized winged creatures, omnivores, able to walk upright on their back paws, with three fingered hands on their arms. They are furred, their wings great leathery bat things coming from the centers of their backs. A thick, short tail serves to balance their tops. They started off as pets of the Builders, and inherited the planet after the Builders left.
The Eleena are slick, silvery creatures without eyes, and with six tentacles depending from their undersides. Adults are cat-sized, with their young much smaller. They evolved from parasitic creatures, their tentacles designed to tap into nerves and blood vessels of their hosts.
In combination, the two are symbiotes. The Eleena enhancing the intelligence of the Losonta to sapient levels through their attaching tentacles. The Losonta deliberately introduce Eleena juveniles into their children after birth, the Eleena burrowing in under the skin of the neck, and penetrating into the brain through the unclosed areas of the babies' skulls. There the Eleena attaches, and begins secreting hormones which gradually change the shape of the skull and enhance the Losonta's brain. The Losonta can feel the Eleena in their skulls, and can dimly communicate, as they remain separate beings.
Humans refer to the Losonta/Eleena pair as Pucks.
The gas giant core is now an earth sized world, called Sheelin by the Losonta, and Midsummer by the Humans. It is swathed in the atmosphere of the Necklace, and richly sprinkled with lush islands in a world ocean. In addition, floatweed mats hang in the air, floating by hydrogen-filled bladders, and trailing long tendrils linking the mats to the ocean and islands.
Losonta have the Cultural Traits of Carefree 2, Audacious 2, and Roguish 3. Their sight is superb, their sense of taste as accurate as human sight, and their touch sensitive. Their hearing and sense of smell are weak, and Losonta don't have any external ears.
