Hunter-Gatherer Norns, once available at The Rise of Norn Civilization, are a genetic breed for C1, bred by Zab (Elizabeth). They are the result of an experiment similar to the Cardinal Norns. These Norns probably have slightly increased intelligence and eating habits. They follow the herds of carrot beetles and gather food. Most like to hang around the island. (They have lived in a Grendel and weed free world.) They use the Purple Mountain Norn sprites due to a prolific Norn named Nate who had about 10 kids, bred with his female kids and his mother until every single Norn in Albia looked just like him.
