Planetary History[edit]

Clan Invasion[edit]

Avon was conquered by both Clan Smoke Jaguar and Clan Nova Cat during the Fifth Wave of Operation REVIVAL in November 3051. Against the Second Amphigean Light Assault Group were arrayed the Smoke Jaguars' Fifth Jaguar Regulars, Fourth Jaguar Dragoons and 214th Jaguar Dragoons, and the Nova Cats' 274th Battle Cluster and 449th Assault Cluster. Initially the two Clans landed only one Cluster each, but even this was too much for the Second to contemplate engaging in open battle. Knowing they could not defeat their foes conventionally, the defenders instead began a short but fierce guerrilla campaign aimed at destroying as much of the Clans' supplies as possible. Entire companies of 'Mechs attacked Clan supply depots under the cover of darkness, though in truth their attacks were merely diversions to allow commando units to infiltrate and plant explosives among the supplies. As a result of such "perfidious" tactics, the Smoke Jaguar commander ordered a "headhunter" Star to locate and destroy the Second's command post. The unit succeeded during a ruthlessly brutal strike that killed the entire command staff. Bereft of leadership the defenders' efforts began to falter, until finally the Second Amphigean was destroyed just days later from an attack by the 214th Jaguar Dragoons.[33]

Operation BULLDOG[edit]

Avon was successfully invaded in the first wave of Operation BULLDOG by the Fourth Pesht Regulars; the defending First Nova Cat Guards were integrated into the Draconis Combine.[34][35][36] The planet was presumably subsequently lost and then recaptured in the second wave of Operation BULLDOG by the 198th Division, Third Royal Guards, Fourth Pesht Regulars, Eleventh Alshain Avengers, First Star League Nova Cat Guards (Alpha), First Star League Garrison Cluster, and Third Star League Garrison Cluster. The defending Beta Galaxy Command Trinary and First Jaguar Guards quickly lost the planet.[37]

The Jihad[edit]

On 24 July 3072, the renegade DCA Kirishima-class cruiser DCS Urizen II was destroyed in the Avon system by the Clan Nova Cat Black Lion-class heavy cruiser and flagship Severen Leroux.[38][39]


The Matabushi Incorporated plant located near the city of Fresno on the Albion continent continued to produce both Union and Overlord-class DropShips for the Combine and for Clan Nova Cat throughout the Jihad,[40] despite having lost more than a third of its capacity during the conflict.[41] The Matabushi plant had been restored to full operating capability well before 3081.[42]

The Matabushi plant wasn't the only plant on Avon to manufacture items to Clan specifications in support of the Nova Cats; Luthien Armor Works also maintained a small LAW-Barcella facility on the planet to manufacture OmniMech components and second-line BattleMechs solely for the Nova Cats.[1]

ilClan Era[edit]

When the Rasalhague Dominion successfully mounted a limited offensive towards Luthien in June 3152, Avon was left as the last world directly between the Combine's capital and any future attack upon the Black Pearl.[43]

Military Deployment[edit]


Avon has three continents named Albion, Britannia, and Norman; the continents are covered in plains which are often subject to high winds.[1][2]

Planetary Locations[edit]

  • Fresno: a city located on Albion[40]
  • Home Plains: grassy plains[49]
  • Stratford: the planetary capital city, located on Albion[1][2]
