Erun Oncant, the ordinary son of ordinary parents, lived in Cardoney. That is, until chosen by a dying dragon to be the rider for her unhatched daughter.
As he took the sword from her dying body, it became instilled with magical powers, and all that remained of her flowed into it.
The egg hatched into the first ever yellow dragon, a colour never seen before and only talked about in legend, and with the help of Princess Lelia from the Kingdom of Vanticor, he cared for her, as she grew to full size. Her name, inherited from her mother, became Corella.
Tensions between surrounding Kingdoms had developed into all out war under the influence of a wizard of immense power. All feared that Cardoney would be next.
Erun and Corella having forged an inseparable bond, together set out to foil the evil machinations of the wizard and restore peace to the world.
