== Planetary Info ==
'''Twycross''' is a weather-wild desert planet that orbits a large and hot sun, where cataclysmic events and powerful wind storms are common, and its people are used to this. Due to these storms and events the population placed their cities and towns underground or made surface structures squat and flat. Twycross has a massive and continuous storm known as the [[Diabolis]], which spawns never ending destructive weather.<ref name=HSp170/><ref name=ocp5/>

In the outer reaches of the Twycross system lies the world known as [[Jonah’s Reach]]. This uninhabitable planet became the Inner Sphere's major source of [[HarJel]] when Clan Diamond Shark acquired the system.<ref name=MMp153/><ref name=ocp6>''Objectives: Clans'', p. 6</ref>

== Planetary History ==
=== Early History ===
Twycross was settled during the height of the [[Star League era]].<ref name="H:RWp159"/><ref name="ER:2750p37"/>

=== Star League ===
During the last years of the [[Star League]], Twycross supported a garrison of [[Star League Defense Force]]s.<ref>Field Manual: SLDF, p. 255, "SLDF - Lyran Commonwealth Military Command Map"</ref>

=== Late Succession Wars ===
By [[3025]], Twycross had become part of the Lyran Commonwealth's [[Tamar Pact]], but it had a low population and was the most undeveloped world within the province. Due to the nature of the planet, its government had become politically sly and subtle in how it conducted business. The justice inflicted on its people was rough even for a world living on the edge of civilization.<ref name=HSp170/>

=== Clan Invasion ===
==== Twycross Invasion of Clan Jade Falcon ====
In June of [[3050]], Clan Jade Falcon invaded Twycross as a part of the [[Clan Invasion]]'s Second Wave of attacks. The planet's defenders, the [[Twycross TMM]], faced off against the [[Jade Falcon Guards (Clan Jade Falcon)|Jade Falcon Guards]]. The militia unit put up a fanatical struggle against the Clan invaders but after three weeks of fighting, the survivors of the Twycross TMM withdrew from the planet. However, though losing the planet, they brought intelligence that aided the [[FedCom]] High Command in developing a strategy to overcome the [[Clans]].<ref>''Jade Falcon Sourcebook'', p. 39, "Second Wave Twycross" - Invasion of Twycross, and its impact on the war.</ref> It was here the [[1st Somerset Strikers]] stole equipment from Jade Falcon to help close the Inner Sphere's technological disadvantage from the Clans.

==== Second Battle of Twycross ====
{{main|Battle of Twycross}}
In September 3050, during the Fourth Wave of the invasion, a FedCom Task Force of several frontline combat units was deployed to Twycross. The task force consisted of [[10th Lyran Guards]], [[9th FedCom RCT|9th FedCom]] [[RCT]], and first two [[battalion]]s of the [[Kell Hounds]]. The Jade Falcon defenders only consisted of the Jade Falcon Guards and elements of the [[Jade Falcon Eyrie (Clan Jade Falcon)|Jade Falcon Eyrie]], which engaged the FedCom forces on the Plain of Curtains and in the Great Gash canyon region. The battle turned in favor of the FedCom forces when Clan forces were lured into the Gash where [[Kai Allard-Liao]] detonated pre-planted powerful explosives in the walls of the Gash, resulting in the Jade Falcon Guards' destruction through being buried under tons of rock and rubble. The destruction and defeat of the Guards triggered the resignation of the Falcon's [[Khan]], [[Timur Malthus]].<ref>''Jade Falcon Sourcebook'', p. 28, 42, "Fourth Wave: The Falcon Falter" - History and background of fight for FedCom counterassault on Twycross.</ref>

Control of the planet was short-lived, as in November 3051, Gamma Galaxy of the Steel Vipers used the Diabolis Sandstorms against the defending Tenth Lyran and Ninth Federated Commonwealth RCTs. The 423rd and 428th Assault Clusters met the Tenth Lyran on the Plain of Curtains while the 94th Battle Cluster drove the Ninth FC from their defensive positions in Schreuder Heights back to the spaceport at Camora. A few hours later,  the FedCom forces lifted off planet.

=== Refusal War ===
In November [[3057]] [[Clan Wolf]]'s Khan [[Natasha Kerensky]] led Clan Wolf forces to Twycross where they battled with the Falcon Guard as part of a massive [[Refusal War|Trial of Refusal]]. In the the ensuing Combat Trial, Khan Kerensky initiated personal ''[[zellbrigen]]'' with Falcon Guard MechWarrior [[Joanna]]; the two battled in the Great Gash canyon, where the battle for Twycross was won for the Falcons when Joanna felled Kerensky in a last-ditch act of defiance.<ref>''Shattered Sphere'', p. 84, "Twycross and Wotan" - Bit piece of Outcome of Trial of Refusal on Twycross.</ref><ref name=MMp153/>

=== Falcon Incursion and Diamond Shark Conquest ===
In [[3064]], the Jade Falcon [[Occupation Zone]] became the target of [[Operation AUDACITY]], the [[Lyran Alliance]] [[Operation Audacity|counter-offensive]] against the [[Jade Falcon Incursion (3064)|Jade Falcon Incursion]]. In Late October to early November, a Lyran Alliance task force led by [[General]] [[Archer Christifori]] challenged the garrison commander, [[Star Colonel]] [[Ravill Pryde]], to a [[Trial of Possession]] for control of Twycross. On the 24th of November [[Archer's Avengers]] were in the process of landing when Ravill Pryde's ''[[Timber Wolf]]'' fired on the incoming DropShips. Seen as a breach of ''zellbrigen'', the Avengers attacked the Jade Falcon Guards with full force, winning the ensuing battle. Captured and briefly made into a [[Bondsman]], [[Diana Pryde]] was used to relay a message to Khan [[Marthe Pryde]] to end her conflict in Lyran space.<ref>''Operation Audacity'', p.??{{cn}}, Twycross is invaded by Archer Christifori during Falcon Incursion of 3064 and used to catch attention of the Falcons.</ref>

The Avengers detached their [[Combat Vehicle|armor assets]] and other miscellaneous forces to garrison Twycross, while the Falcons resolved to never return to Twycross. However, in April [[3065]], [[Clan Diamond Shark]] issued a ''[[batchall]]'' for control of the planet. After five days of fighting the garrison force was dispatched and Twycross became a possession of Clan Diamond Shark. The Sharks had originally wanted the planet for its disabled [[BattleMech]] factory, but later scouts from the Clan discovered that a nearby orbiting planetoid in the system - Jonah's Reach - possessed a large deposit of HarJel.<ref>''FedCom Civil War'', p. 120, "Falcon Incursion" - Events of the Lyran Alliance invasion of Falcon's OZ leads them to Twycross and its falling to the Diamond Sharks.</ref><ref>''Field Manual: Update'', p. 58, "Diamond Sharks" - Debt Consolidation - Reaffirming planet takeover and what happened to the Avengers on planet.</ref><ref>''The Wars of Reaving'', p. 19</ref>

=== Jihad Era===
By [[3077]], Twycross's old [[Trellshire Heavy Industries]] facility had been restored and re-configured to produce Diamond Shark designs for sale and Twycross had become the most prized Diamond Shark possession in the Inner Sphere. The Clan's flagship, the ''[[Nightlord]]''-class battleship [[Terror of the Deep|DCS ''Terror of the Deep'']], and a [[Galaxy]] of troops had been assigned permanently to defend Twycross and the [[HarJel]] mining complex on Jonah's Reach.<ref name=MMp153/>

During the [[Bloody Tricentennial]] attacks the Trellshire Heavy Industries plant was destroyed in a nuclear explosion intended to both destroy the factory and the garrisoning Diamond Shark forces from [[Gamma Galaxy (Clan Diamond Shark)|Gamma Galaxy]], who had been lured to the plant by a series of earlier explosions.<ref name="FM:3085p115">''Field Manual: 3085'', p. 115, "Gamma Galaxy"</ref> The plant was initially described as having been heavily damaged.<ref name="J:FRp113">''Jihad: Final Reckoning'', p. 113, "Clan Industry"</ref>
