The two-headed natives of the land of Meracchia have a strong "duality" theme both to their bodies and to their culture. They were the first to formalize magic as a science, and while this doesn't always work perfectly, the spirits that drive magic are usually happy to play along with what mortals think the rules are.

Were they two-headed normally, or is it a thing they do a la Vassa?
