The Acamar system is the location of at least one inhabited planet, Acamar VIII—usually referred to simply as "Acamar." The Acamar system has ten planets[1] and a substantial asteroid belt named Illeudian, which is the site of a number of mining operations.[2] As of 3145, Acamar is located in the Tikonov Commonality region of the Capellan Confederation.[3]

System Description[edit]

Acamar is located near the Woodstock and Bex systems.

System History[edit]

The Acamar system was surveyed by a team from the planet Tikonov in the early twenty-third century, who identified a habitable world in the system. The Acamar system wasn't considered to be suitable for colonization at the time, but was subsequently settled after the discovery of extensive deposits of titanium ore, gold and silver which made the system highly desirable to House Davion, House Liao, and House Marik.[1]

Acamar is the eighth planet in the Acamar system.[1]

Planetary History[edit]

The survey team who surveyed Acamar described the world as a constant winter wonderland. Following the discovery of extensive titanium, gold and silver deposits Acamar was settled by colonists who were undeterred by the planetary climate. The bulk of the population settled in the large Trans-Mahn and Tomahn Moraine valleys and this region would continue to remain the most densely populated region of the planet until at least as late as the Dark Age. The planetary capital, Kalskag, was founded in the northeastern region of the Tomahn valley; southwest of Kalskag a large silver mine was located in the Tokal Mountains and the city of Flat was founded nearby, growing to become the second-largest city on the planet and the main center of trade. The city of Huss was founded in the Trans-Mahn valley. The colonists also exploited the Marsa Mountains, which became the source of the bulk of the mineral wealth mined by the population.[1]

Despite the interests of the various neighboring states Acamar was incorporated into the Terran Hegemony by the mid-twenty-fourth century.[5]

Amaris Civil War[edit]

When Stefan Amaris launched Operation APOTHEOSIS, his takeover of the Terran Hegemony in December 2765, special forces teams were activated on every one of the member-worlds of the Terran Hegemony. Their mission was to seize control of every HPG station in the Hegemony an hour before APOTHEOSIS began. Acamar was one of just three worlds where the attempt by the Rim Worlds Republic to capture the local HPG transmitter saw the transmitter destroyed, due to heavier than anticipated local resistance.[48]

Succession Wars[edit]

Acamar became a part of the Capellan Confederation and the local nobility maintained their loyalty to that nation even after the world fell to the Federated Suns after forming part of the short-lived Tikonov Free Republic during the Fourth Succession War which saw power swing to the merchants on the planet.[49][50]

Fourth Succession War[edit]

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. Acamar was one of the systems incorporated into the Republic.[20]

Clan Invasion Era[edit]

Operation GUERRERO saw the creation of the Chaos March but Acamar did not fall to the Capellan Confederation, instead gaining dubious independence. A few years after the creation of the Chaos March, the local conflict flared after the Tiger Sharks mercenaries arrived on planet and led to a mutually destructive round of fighting between the nobility based in the capital Kalskag and the merchants based in the city of Flat. Later still, in 3061 an invasion was mounted by a mercenary force led by General Motors of Kathil and Johnston Industries of New Syrtis in Operation STILETTO which had the aim of bringing Acamar and Genoa back into trade arrangements with these Federated Commonwealth industries who had come to rely on them since 3030s.[49][50]

FedCom Civil War[edit]

As of 3066, Acamar was noted to have a rather weak government, with the real power held by large mining corporations and the families owning them. This proved problematic when the Capellan Confederation hired Olson's Rangers to attack the planet in October 3066. The privately hired smaller mercenary units on Acamar refused to cooperate with the government or even each other, stubbornly defending only their assigned objectives and being destroyed one by one as a result along with the planetary militia and the government-hired Peregrine's Hussars mercenary command.[51]

The First Cunningham's Commandos were eventually brought in to defend the planet against Olson's Rangers (who were pretending to be a much larger force than they actually were).[52][53]

By this time the asteroid belt Illeudian was home to numerous mining operations and the headquarters of those various operations.[1] Pickets (sensor platforms) had been stashed in the asteroid belt that could identify incoming vessels, such as identifying three supposed Mule-class DropShips to be in fact an Overlord and two Unions.[2]


During the Jihad, Word of Blake sympathizers in the government ordered the Acamar militia to lay down their arms.[1] This brought Acamar into the Blakist Protectorate by 1 August 3068[38] without a shot being fired. As a result, Acamar didn't suffer greatly during the horrors of the Jihad.[1] Acamar was invaded by allied coalition forces operating on the Federated Suns front of Operation SCOUR in January 3078; the most significant casualty of the battle for control of Acamar was the death of AFFS Marshal Katheryn Sandoval-Ito, who was succeeded by Marshal Jon Davion.[54] Marshal Sandoval-Ito fell in battle on the 7th of January, her Devastator BattleMech swamped by Word of Blake Purifier and Se'irim battle armor until it fell.[55]

After the Jihad, a native of Acamar became the Chairman of the Capellan Transitional Council, the advisory body established alongside the Capellan Transitional Government to ease the transition of former Capellan worlds into the newly formed Republic of the Sphere. The Chairman, Su Xiaose‎, was mayor of Hess during the Jihad and led an anti-Blakist resistance movement on the world during the Word of Blake occupation of Acamar.[56]

Dark Age[edit]

The Liao government traditionally gave Acamar's nobility the lion's share of profits from the planet's gold and silver trading, and so the nobles remained as staunchly pro-Liao in the Dark Age as they had always been. The merchant class, however, chafed under the status quo.[1]

In November 3132, a Bannson's Raiders Band of Five raiding party, led by Bill Maignlov, attacked a Belyakov-Ourobouros scrapyard on Acamar. They were repelled by the Swordsworn's Prince's Men.[57]

News arriving to Fletcher by DropShip Junebug in 3135 told that Capellan Confederation forces had used a nuclear weapon in their conquest of the planet. Sensor reading from the DropShip showed that when militia forces downed a Phoenix Hawk, the defenders reported a small truck racing from the Capellan lines toward the gate as the rest of the defeated assault force fell back from Valis City. In the next instant, the communications console exploded in a flood of static and his fellow crew members reported seeing the fireball on the ship‘s screens. The explosion was much more than just a BattleMech's fusion reactor failing, those readings that could be recovered from the damaged sensors of the Junebug indicate that the detonation was of a higher magnitude that would be expected from the destruction of a medium BattleMech such as a Phoenix Hawk. Since the forces of House Liao have taken Acamar and blocked direct traffic to and from the planet, further information has been unavailable.[58]

Military Deployment[edit]




- The unit was operating at 115% strength, with 15% of their equipment featured Clan and 90% Star League technology.


Acamar has three continents and a very large island group, but only the continent of Katenga was suitable for colonization. Situated in the planet's equatorial region, even this continent was not immune from Acamar's winter storms. Katenga has two large valleys where most of the planet's population was located. Trans-Mahn is the southern valley, where the Mahn River flows. The Osz Forest covers the northern approach to the valley, where the Otal foothills separated Trans-Mahn from Tomahn Moraine. Tomahn is the larger of the two valleys. Southwest of the Tomahn valley lies the Tokal Mountains, which are rich in silver. Acamar's remaining continents of Tamarack and Asta are in the northern hemisphere where they are frozen year-round, making them impossible to settle.[1]

East of the Katenga coastal plain between Flat and Kalskag is the Marsa Plateau, also referred to generally as the "badlands," thousands of square kilometers of arroyos and canyons. Beyond these are the Marsa Mountains were rich in mineral wealth.[2]
