DnD 5E: Dux Irontooth

Dux Irontooth [LE kobold fighter] was born a slave, and spent a lot of his formative years muzzled due to his habit of being a yapper. As an adult, Dux earned his freedom by becoming a slavecatcher. He's an evil little shit who'll take any bounty for coin, and his only real spark of honour is that he always finishes his jobs - he comes back with the bounty, or not at all.
