Small reptilian lifeforms native to Uljghersn. Urgts apparently evolved from nearly immobile creatures called Klergts. The key component to increased mobility being a more effective respiratory system. Urgts are the prime responsible for the existence of life in Ulfghersn since they recycle Sjurgh much faster than the Klergts, reportedly the first lifeforms to exist in the planet. For some reason the Urgts seem to have a mostly stable DNA and the ratio of mutations is extremely low, making Urgts extremely resistant to any biological changes through generations.
Skäetr scientists are currently trying to understand this phenomenon, which they believe could aid in the creation of self-replicating biomechanical structures immune to evolution.
