The Great Mhunna is a rather large Mhun, massively bodied and six feet tall, taller than any of his brethren. He is also the leader of Moghedu. He is very brusque with outsiders, as are most mhuns of Moghedu, and has a strong tendency to keep an eye out for race number one, the Mhun. Historically he has helped (or hindered, in the case of Mhaldor) Sapience in mysterious ways, often at a high monetary price.
It should be noted that "Mhunna" is a title of office, rather than a name given at birth.
