Ripa 'Moramee

Ripa 'Moramee was a Sangheili warlord and military commander who served as the Arbiter of the Covenant during the beginning of the Great War. 'Moramee was ruthless and unrelenting, concerned more with victory and glory over honor. Though known for his intense rage and savagery, 'Moramee was an extremely effective commander and a highly talented strategist.
Serving the Covenant's Ministry of Preservation with glory during the 23rd Age of Doubt, 'Moramee rose through the Covenant's ranks after subduing many civil conflicts within the empire, most notably quelling the Sixteenth Unggoy Disobedience and Krith's heretical reign. After being captured and imprisoned for leading a failed coup d'état against his kaidon on his homeworld of Malurok, 'Moramee was given the title of Arbiter by the Hierarchs, mainly at the urging of the High Prophet of Regret who sought to use 'Moramee's ruthlessness against the emerging human threat.
In his new role, he was given command of the Fleet of Glorious Interdiction and led the Covenant's renewed campaign on Harvest, excavating a Forerunner artifact on the planet's surface. Towards the end of the campaign in February 2531, he assisted the Prophet of Regret in an attempt to reactivate a dormant Forerunner fleet on a Forerunner shield world. This led to a series of violent engagements against forces led by Captain James Cutter of UNSC Spirit of Fire. Ultimately 'Moramee was killed by Sergeant John Forge in the shield world near the end of the battle.
