__TOC__

==Description==
The '''Epsilon Eridani''' system consists of a class K2IV primary orbited by ten planets.<ref name=DARWp238/><ref name=TP_EE_p3/> and is home to at least one habitable world, '''Epsilon Eridani IV''', which as of [[3145]] was located in the [[Republic of the Sphere]].<ref name="ER:3145p38"/><ref name="FM:3145pVI"/>

==System History==
Epsilon Eridani was settled during the early years of the [[Terran Alliance]], with the first colony on Epsilon Eridani IV being established by [[Alana Korvin DeVall]] at some point prior to [[2208]].<ref name="HLTCCp64"/>

===Planet History===
====Early History====
The world known as Epsilon Eridani was first discovered in [[2050]] by the Terran Alliance probe [[Magellan Program#Magellan One|Magellan Four]].<ref>''House Davion (The Federated Suns)'', p. 9: "Early TA unmanned probe discovers Eridani"</ref> The Terran Alliance explorer [[Alana Korvin DeVall]] helped found the Epsilon Eridani colony at some point prior to [[2208]],<ref name="HLTCCp64"/> and Epsilon Eridani was one of the worlds that remained a part of the Terran Alliance following the [[Outer Reaches Rebellion]] and the [[Demarcation Declaration]] of [[2242]],<ref name="HB:HMp16"/> later becoming one of the worlds within the [[Alliance Core]] region of the Terran Hegemony.<ref name="H:RWp159"/>

Circa the mid-twenty-second century, one of the [[slowboat colonization]] ships that had left [[Terra]] prior to the FTL first ships' creation arrived at Epsilon Eridani to find a burgeoning colony already established by [[Terran Alliance]] [[JumpShip]]s. The Alliance, who had a long memory for dissidents, turned those missions into laughingstocks and not the historical achievements they were.<ref name="JCIP2p66>''Jihad Conspiracies: Interstellar Players 2'', p. 66: "Terrelibre"</ref> It is not known what happened to those colonists.{{cn}}

====Amaris Civil War====
During the [[Star League]] era Epsilon Eridani became the site of the Army Headquarters for the [[SLDF]] [[5th Army (Star League)|Fifth Army]],<ref name=H:LoTV1p43>''Historical: Liberation of Terra Volume 1'', p. 43: "5th Army"</ref> the administrative headquarters of the first region of the [[Capellan Confederation]] and a series of training bases, many of them major.<ref name="H:LoTV1p84+"/> With the eruption of the [[Periphery Uprising]] in [[2766]] the Fifth Army found itself responsible for the entire Capellan Confederation, and even though the Fifth Army received some reinforcements drawn from the [[1st Army (Star League)|First Army]]<ref name=H:LoTV1p43/> this greater astrographical area of responsibility naturally led to the Fifth Army being stretched thin.<ref name="H:LoTV1p84+"/>

When [[Stefan Amaris]] launched his coup on the 27th of December 2766 on [[Terra]] his forces also swung into action on all of the other worlds within the Terran Hegemony and a number of jointly administered worlds.<ref name=H:LoTV1p80>''Historical: Liberation of Terra Volume 1'', p. 80: "Cometh Hell's Legions"</ref> This included Epsilon Eridani; despite the Fifth Army being deployed across the Confederation there were still a large number of personnel from the Fifth Army on Epsilon Eridani, as well as a substantial number of SLDF personnel within the support and training organizations. These people, primarily administrative, support and logistics personnel, posed a risk to the [[Rim Worlds Republic]] forces, which had already managed to occupy at least one [[Castle Brian]] on Epsilon Eridani prior to the Coup beginning.<ref name="H:LoTV1p84+"/> The '''SLS ''[[Antietam Creek]]''''' was a black navy ship from the [[SLDF]] attached to the Second [[Battalion]] of the [[83rd BattleMech Division|Eighty-Third BattleMech Division]] when the unit tried to escape from [[Epsilon Eridani]] during the [[Amaris Coup]] in [[2767]].<ref>''Lawyers, Guns, & Money''</ref>

The Republican forces hadn't been able to establish a foothold within any of the training facilities or the Military Region administrative headquarters, and as a result when they launched their campaign to take control of Epsilon Eridani they bombarded the Castle Brian housing the Military Region HQ with multiple nuclear weapons while also hitting the various training bases with a combination of nuclear and biological attacks. While these attacks were largely effective, the Republicans didn't manage to hit every training base, nor were they able to track down and hit every location where SLDF equipment was stored; they also failed to capture or destroy all of the war matériel stored across Epsilon Eridani awaiting shipping to the Periphery front. Epsilon Eridani subsequently became a hotbed for resistance against the Republican forces and Stefan Amaris as the SLDF personnel who survived the initial attacks made use of the remaining equipment to form and lead resistance groups across the planet.<ref name="H:LoTV1p84+"/>

The AEAF orbital bombardment of Epsilon Eridani included strikes on the planetary capital, Madison, which was located on Parassus; the bombardment almost levelled the city, including the Star League mint which was located in the city and was responsible for printing Capellan currency.<ref name=DARWp238/>

After the capital Madison was bombarded by the Rim Worlds forces, many residents of the city found shelter inside the [[Harvard Company, Inc.]]'s aerospace components factory. Once Amaris landed those survivors were subjected to a brutal massacre and the factory was razed to the ground.<ref name=EESLG19043080>''Epsilon Eridani's Star League Ghosts!''</ref>

====First Succession War====
With the outbreak of fighting after the fall of the Star League, Epsilon Eridani surrendered itself to [[House Liao|House Liao's]] [[Ariana Grenadiers]] and [[Justinia's Cuirassiers]]. This was part of House Liao's first campaign during the [[First Succession War]] to claim former Terran Hegemony worlds between [[2780]] and [[2800]].<ref>''House Liao (The Capellan Confederation)'', p. 45: "Eridani E surrenders to Liao forces in First Succession War"</ref>

====Third Succession War====
In [[2944]], House Liao's [[First Chesterton Voltigeurs]] repelled a [[Free Worlds League]] raid on Epsilon Eridani. The unit had fended off the attack by Marik forces with heavy losses in air and ground support.<ref>''House Liao (The Capellan Confederation)'', p. 83: "1st Chesterton Voltigeurs" - Unit action during the Third Succession War on Epsilon Eridani</ref> In the last years of the [[Third Succession War]], [[Laurel's Legion]] was able to make a blunt move to take the planet from [[Federated Suns]] forces in [[3024]].<ref>''House Liao (The Capellan Confederation)'', p. 83: "Laurel's Legion" - Unit profile shows it fending off Davion attack in 3024</ref>

====Fourth Succession War====
Following negotiations between [[Colonel]] [[Pavel Ridzik]], chief military advisor to [[Chancellor]] [[Maximilian Liao]], and [[AFFS]] [[Lieutenant General]] [[Ardan Sortek]], conducted in February [[3029]] Ridzik created a new nation, the [[Tikonov Free Republic]]. The Republic was created by incorporating those worlds of the [[Tikonov Commonality]] that hadn't already been conquered during the first half of the [[Fourth Succession War]]. Ridzik returned to [[Elgin]], the new capital of the Tikonov Free Republic, on the 3rd of March 3029 and swiftly began implementing a new government consisting of family members, friends and other appointees loyal to himself, purging dissident elements on the various Republic worlds and taking the opportunity to settle old scores. Epsilon Eridani was one of the systems incorporated into the Republic.<ref name="FSWMAv2p16"/>

====Eridani Civil War====
In [[3062]], the mercenary units [[Kingston's Killers]] and [[The 48th]] were hired to take part in a small conflict on the side of the [[Palatine of Duvic]] faction against the County Shu faction. This conflict would find the Kingston's Killers to be all but destroyed and the Palatine of Duvic faction found guilty of conspiring with the [[Word of Blake]] against the planetary government.<ref name=ItW/> The 48th were reported to be cleared of all wrongdoings by the local authorities when evidence of their employers’ corruption came to light.<ref name=MSU_24>''Mercenaries Supplemental Update'', p. 24: "The 48th"</ref>

Major [[Kingston Crawford]], for whom the unit was named, died at the hands of a reinforced light lance of the Shu County Volunteer Battalion BattleMechs, called the Vigilantes (formerly Veck's Vigilantes, after the previous unit commander), commanded by Commander [[Tybalt Kelly]]. Kelly's lance consisted of his ''[[Lineholder]]'', a ''[[Raven]]'', a ''[[Javelin]]'', and a pair of ''[[Commando]]''s. Both the ''Javelin'' and one ''Commando'' were lost in the fight with Crawford's ''[[Pillager]]''. [[Michio Namihito|Major Namihito]], commander of The 48th, was involved in uncovering the collusion between the Duvic Palatine and the [[Word of Blake]].<ref name=ItW>''Initiation to War''</ref>

In [[3067]] two mercenary units, the [[Lone Star Regiment]] and [[Redfield's Renegades]], were battling on Epsilon Eridani when they made a significant discovery. The fighting near the Shamus Mountains unearthed an old [[Star League Defense Force]] depot hidden within the mountains. Still intact within the Depot was a functioning ''[[Colossus (DropShip)|Colossus]]''-class [[DropShip]] in pristine condition. Both mercenary units immediately laid claim to the DropShip, and with neither willing to compromise a grueling combat was initiated that saw both units take heavy casualties. Ultimately, the Lone Star Regiment were the victors and recovered both the DropShip and the battlefield salvage as prizes.<ref name="TRO3075p198">''Technical Readout: 3075'', p. 198: "Colossus"</ref>

====The Jihad====
The [[Word of Blake]] assimilated Epsilon Eridani into their [[Word of Blake Protectorate|Protectorate]] early in the [[Jihad]], and it would remain a Blakist world until February [[3078]]. Forces from the [[Federated Suns]] front of [[Operation SCOUR]] liberated Epsilon Eridani on the 22nd of February after a fiercely fought [[Battle of Epsilon Eridani (3078)|week-long battle]] against the defending [[Epsilon Eridani Protectorate Militia]] forces.<ref name="J:FRp58">''Jihad: Final Reckoning'', p. 58: "The Jihad in Review"</ref> The assault on Epsilon Eridani was one of - if not the - first assault to be performed on the Federated Suns front since command of the front passed to [[Marshal (rank)|Marshal]] [[Jon Davion]] following the death of [[Field Marshal]] [[Katheryn Sandoval-Ito]] on [[Acamar]]. Leading Group III of the Federated Suns front personally, Davion deployed the allied coalition forces via a combined arms suborbital drop strategy that he had developed during his time at [[Sakhara Academy]]. The drop allowed the coalition forces to strike directly at the Blakist leadership on Epsilon Eridani, decapitating the [[Word of Blake]] forces on the planet within the first 24 hours of combat operations and restoring civil law to the capital within a week. Despite the overall success, Blakist forces utilized fast hovercraft and battle armor hunted down [[Clan Nova Cat|Clan Nova Cat's]] [[Delta Galaxy (Clan Nova Cat)|Delta Galaxy]] ''[[Arbalest]]s'' and other ECM-equipped units early on in order to prevent disruption of their C3 networks. Due to that, Nova Cat casualties were high.<ref name="JHS:Tp71">''Jihad Hot Spots: Terra'', p. 71: "Epsilon Eridani Liberated"</ref><ref>''Technical Readout: 3085'', p. 142: "Arbalest"</ref>

The Federated Suns News Service held up the smooth transition in leadership between Sandoval-Ito and Davion as an example of how closely the [[Marshal of the Armies]] had been involved in planning the Federated Suns front of SCOUR, and held up the quick campaign by Group III as an example of how the Group was a genuinely integrated force. The FSNS also included a human interest piece to substantiate the claim for easy integration, detailing an American Football match on Epsilon Eridani on or around the 22nd of February that saw a team consisting of members of Clan Nova Cat's Delta Galaxy augmented by personnel from the [[Drake's Drivers]] mercenary unit on one side and an [[LAAF]] offensive line on the other team, backed up by runners and receivers from the [[Benjamin Regulars]] and fielding a [[Com Guards|Com Guard]] quarterback.<ref name="JHS:Tp71"/>

====Republic Era====
The city of Madison, rebuilt after the Amaris Civil War, continued to serve as planetary capital during the rule of the Republic of the Sphere. Madison was located 370 km northwest of Dori, the large port city located on the shores of Lake Arous which was itself the center of Epsilon Eridani's commercial industry.<ref name=DARWp238/> It was here that [[Malcolm Buhl]]'s faction of [[ComStar]] built its primary base of operations in the planet's second newly recovered SLDF depot. In February of [[3141]] after the reborn [[1st_Division_(ComStar)|First Division]] had made itself known and were chased from their ''Omega'' base on [[Luyten 68-28]]. It was here that the new Com Guards would attempt a fighting stand against the [[RAF]]. After 10 days of brutal fighting, the [[Republic of the Sphere|Republic]] forces of [[Stone's Revenants]] and the [[XIV Hastati Sentinels]] had effectively destroyed the Blessed Order.<ref>''Field Manual: 3145'', p. 140</ref><ref>''Turning Points: Epsilon Eridani'', p. 7: Avenging Angels''</ref>

===Geography===
Epsilon Eridani is a pleasant but damp world, prone to frequent mild rainstorms. The two major continents are the southern continent of Gousha, which is divided primarily into a mix of swamplands and rainforest, and the northern continent of Parassus, which is rockier and drier than Gousha but still prone to frequent rain. Located on Parassus is a large lake named Lake Arous.<ref name=DARWp238/><ref name=TP_EE_p5>''Turning Points: Epsilon Eridani'', p. 5: Atlas</ref>

===Planetary Locations===
{{scrollbox|

== Notes ==
* ''[[Jihad Hot Spots: Terra]]'' states that during the Jihad, Epsilon Eridani was liberated by Group II of the Federated Suns front of Operation SCOUR. This has been noted to be an error; Epsilon Eridani was actually liberated by Group III of the Federated Suns task force.

{{Quote|Epsilon Eridani was liberated by Group III of the Federated Suns thrust.

* Epsilon Eridani IV's number of moons was not been consistent, as older publications only mention the planet only having one moon, such as ''[[Dark Age: Republic Worlds (3130)]]''. However in Robert N. Charrette novel, ''[[Initiation to War]]'', references are made using "moons" (plural). This "two moon subject" then shows up again in ''[[Turning Points: Epsilon Eridani]]'', and goes on to present an orbital view of the planet with two moons on the following page. It was then confirmed to have two moons by BattleTech's Assistant Line Developer, [[Ray Arrastia]].

{{Quote|1=It has a wide elitical orbit. Two moons is correct. The older publication is incorrect (and has been known to contradict other sources).|2=[http://bg.battletech.com/forums/index.php?topic=60715.msg1392855#msg1392855 Ray Arrastia, Assistant Line Developer, 15 Mar 2018]}}
