Here's one of my other favtorite OCs, a character who I played in the DnD adventure, Dragon of Icespire Peak.
He's had a lot of character development, but the initial concept for Delsaur was a Silver Dragonborn Rogue who thinks Dragons are all one big conspiracy to keep the common folk in fear, paying big money to the kingdom's "dragon slayers" for protection. He denies that his ancestry is truly draconic, going as far as being embarrassed by his middle name "Bahamut" after the Platinum god of Dragons. His goal was to disprove the existence of dragons once and for all, but, well... things changed over the course of the adventure! But that's a story for another time. :)
