The Scarlet Moon House of Lords was the upper house of the parliament of the Scarlet Moon Empire and was comprised of various nobles, aristocrats and other high-ranking members of Scarlet Moon society. After the death of Emperor Michelan Rugner in 446, the House of Lords passed an act, under extreme pressure from Geil Rugner, revoking Crown Prince Barbarossa's right to the throne. This act was known as the Abdication Trial.
