Lord Maisenches
From ROI Wiki
Lord Maisenches is an Ahbranai royal, and the ruler of House Carin. He is the mortal enemy of House Monty and seeks to become the single most powerful Ahbranai house in the entire galaxy, even overthrowing the emperor and his house, if possible. He has loyal spies (such as Bradish) in every single house in the galaxy, and among every race, and uses them to great effect in his quest for power. His deception, greed, and craftiness know no limits. However, he is eventually outsmarted, along with the rest of the Ahbranai lords, by Psial, Breakman, and the rebellion forces of the Commonwealth races.
