All Axyllian Dratini can trace their lineage from the Dratini owned by the royal family. Dragon type pokemon were rare before the advent of the power plants, and Dratini were popular pets among the nobles. They were all selectively bred in order to better survive the region's harsh winters. This manifested in an Ice typing and a protective fur coat.
Axyllian Dratini are protected due to their low fertility rate and a program in the Roujelle Mountains is attempting to breed them to better survive in the wild.
