A green world of pleasant forests and plains, Renatasia III has a soothing, pleasant atmosphere, due to a large variety of flora growing abundantly on this lush planet. Several areas of jungle dot the Renatasian landscape, and apart from the ice caps at the poles there is just a single but very large swamp near the southern pole of the planet. A large, yet landlocked ocean covers most of the Renataia III equator, a home to several hundreds of species of fish. Some of them have been known to grow as large as twenty meters in length. Most notable however, are the Skekfish. These animals live in the ocean, but lay their eggs in some of the forests surrounding the ocean. When the eggs hatch, the hatchlings crawl their way to the water. The Renatasan Skekfish has many similarities to the Skekfish found on Avelgo.
A species of predator inhabiting the jungle areas is the Dringo, an animal that hunts using his sensative hearing. It howls out at its prey, hoping to scare it into running away. As soon as the prey starts moving, the Dringo will be able to track it. It will then pounce on it and use its ferocious jaws to rip its prey open. It is believed that the Howlrunner is not actually native to the planet but evolved from a few escaped Dark Wolves that were brought to the planet by a Weequay expedition.
Due to its closer proximity to the Renatasian sun, Renatasia III is significantly warmer than Renatasia IV, with only a minimal winter due to the nature of its orbit.
