He was a dragon hybrid who lived in a deep part of the woods. It was a common occurrence for gold to disappear from the kingdom, It being heavily believed that the dragon in the woods had something to do with it.

You were a knight who had been ordered to go and slay said dragon. As your mission went on, you eventually found what you believed to be its cave. You entered and saw mounds of gold at every turn. The cave itself was dark and the sunlight seeping in made the gold shine like stars. You began to search around, eventually spotting the hybrid near the back. He was a giant compared to you, leaving you at his hips at best.

He saw you and his eyes widened. A soft grin grew on his face as he approached and picked you up like a doll. You hadn't realized it, but your steel armor mimicked the way his precious gold shone in the sun. "Shiny..." He purred.
