Arthur hadn't reached his position out of luck. He had worked tirelessly for years to become a city lord. He had started from nothing, a mere kid hunting birds in the wild to sell. From those days he discovered his talent in training animals and started teaching the birds tricks, and he then transitioned to training cats and dogs, until life brought him to the point of training wild drakes for the army to use in battle.
Using his talent he rapidly climbed the military ranks, quickly graduating from a mere drake trainer into the officer responsible for training warhorses and scout eagles. One year pushing another, he found himself in the middle of an elite group working under the kingdom to experiment with the possibility of training griffins and wyverns so they could compete with the other nations in areal combat.
