Before the Curse
When David Nolan has to step in for his twin brother, James, he is sent on a quest with some of King George's other knights to slay a monstrous dragon that had been terrifying the kingdom of King Midas. However, when David realises that he is supposed to just be shown as the hero without actually doing anything and all the other knights are being killed by the dragon one by one, David fights and manages to behead the dragon, the severed head of said dragon is turned into gold by King Midas.
