Dragon Knight
Knights, a profession usually suited for humans as they equip themselves with weapons. However that didn't stop this demi-dragon from pursing it as his own goal either. Though it took some time eventually he managed to garner enough support to be accepted as such. Granted the title of 'Honarary Knight' when he participated in a monster repelling event and helped keep a city safe.
What made him want to become such? Well it doesn't take much to guess. Honor and the title, the shiny armor only added to the appeal after he had it handcrafted for him by a local smith. Ever since he's been dedicating his life to helping others so that he could quietly build up his own dragon hoard through legal means rather than theft.
