Following the end of the Four Years War between the United Federation of Planets and the Klingon Empire, Admiral Brazeau led the Eighth Fleet to the Rigel system, from which the Klingons had recently withdrawn. The Klingons had spared the Orions of the Rigel system from the scorched earth policy of the Year of Horror to make them appear to be allies of the Empire. The Botchok Planetary Congress was just relieved to not suffer the atrocities, and ordered a triumphant welcome to the Eighth Fleet. Brazeau's ships responded by duly sending their arrival details ahead, as per the Orion Neutrality Act.
On reference stardate 1/9806.29 (c. 2256), Brazeau and the Eighth Fleet arrived and immediately sealed off the Rigel system. They then landed soldiers on the Orion homeworld of Rigel VIII (Botchok) to capture the spaceport and communications centers. With them came the Rigel Demilitarized Zone Commission, to meet with the Botchok Planetary Congress. (FASA RPG module: The Orions: Book of Deep Knowledge)
