The mrran are large, woolly herbivores with the intelligence level of the average dog. They were created by the first Mage Storm following the Cataclysm, changed from something else. Errold was the first to discover the mrran, herding one later named Carpet back to the refugee campsite. Carpet was immediately set to work as a packbeast.
After the village of Errold's Grove was established, Proouw's pack herded more of the animals to the village, where an entire herd was kept. Their wool is useful for making cloth, and the animals are also good beasts of burden.
