Mounts were used to aid kingdom's police and they were eventually transformed into special troops. They were also of tremendous help during the war as they were the primary means of transportation. Since then, the demand for mounts increased and adventurers who visited Erion desired to possess mounts for themselves. Eventually, people from over the continent flocked to Erion and soon, the town got bigger and bigger and became more prosperous. Because the trade of mounts in the town was flourishing, hunting monsters and other related stuffs about mounts became Erion's specialty as they supplied the mount feeds, essences and even eggs.

  As the town prospered, the citizens of Erion also became more adept in dealing with wild and ferocious monsters. Their skills were harnessed to a point that they began to hunt the most dangerous creatures that were ever known to mankind: the "Fenrir" and "Dragon." These mounts were so hard to come by and were even branded as the symbols of "death."

 Erion does not possess a formidable defensive structure like other big towns but they more than compensate for this flaw with their "mount" system.
