Azba Venkaur Hakushaku

Despite being the head of the Venkaur region, he wasn't very wealthy. He eventually decided to start selling military secrets in exchange for a drug known as Vizine. This made him rival the Tuatha Dé. However, the spies of the Alvan Kingdom discovered he was selling drugs and tasked Lugh Tuatha Dé to assassinate him. He completed the request.
