The oltang is a large, green, lizard-like creature that inhabits the swamps and wetlands of Oorzh. Being mostly aquatic, the oltang usually only comes to land when it is voluntarily wanting to shed its skin. The oltang has a long, constantly-shaking tail that produces an electrical current. When a predator or a new potential mate approaches, the oltang will raise its tail high above its head and then slam it down; if the creature is a potential mate, the electrical current will cause an explosion of green sparkles. If the creature is a predator, the shock will usually ward it off.
