Basalt IV, more commonly referred to simply as Basalt, was the fourth planet of ten in the Basalt system and had three moons named Granite, Marble, and Slate.

Planetary History[edit]

Early History[edit]

Basalt was one of the first worlds settled by explorers from the Terran Hegemony. With its vast stores of rare metals and minerals, mining companies eagerly sent employees out to the world. Despite the high gravity, incredible air pressure, and wild weather, the world has long been a source of excellent raw materials.[1]

Age of War[edit]

The Federated Suns invaded Basalt in or around 2445, attempting to capture the world from the Terran Hegemony. The defending Terran Forces were under the command of General "Mad Dog" Marceneaux and resisted the Federated Suns forces fiercely; on the 12th of April General Marceneaux was made aware that the Federated Suns had landed additional forces on the planet, augmenting their ranks with the addition of the Sixth Terran March Corps, a shock corps consisting of six heavy divisions of troops, predominantly composed of tanks and artillery, threatening to overwhelm the defending Hegemony Armed Forces defenders. Unknown to the Federated Peacekeeping Forces a special unit of BattleMechs under the overall command of Major Gabriel Calhoun had also recently arrived on the planet. It was Major Calhoun who informed General Marceneaux at his bunker in Garamondia of the arrival of the Sixth Terran March Corps; even as the FPF forces overran the HAF Ninth Armored Cavalry command posts and continued to push forward, Marceneaux ordered Calhoun and his troops into action against the FPF. The shocking presence of BattleMechs on the field was enough to rally the defending HAF forces.[8]

Succession Wars[edit]

After the fall of the first Star League, the Federated Suns grabbed Basalt. During the Succession Wars the Capellan Confederation tried several times to take the world, but was repelled each time. The most notable instance was during the Fourth Succession War, when the two major cities of the world were attacked by the CCAF in an attempt to halt the Davion advance. Elements of the First Kerr's Intruders, McCrimmon's Light Cavalry, and MacGregor's Armored Scouts landed outside Zander's Delight. They faced the Fourth Davion Guards RCT, taking serious losses, and surrendering to the AFFS after they discovered that the warehouses were empty.[52]

The second Capellan attack was headed by a half-battalion from Warrior House Ijori supported by five companies of the First New Hessen Irregulars. They attacked unexpectedly, dropping forces directly on the warehouses in Controssa. The Fourth Crucis Lancers' Second Battalion bore the brunt of the Capellans' anger once they discovered the warehouses were empty. Unfortunately the Capellans' focus on destroying the Second Battalion allowed the rest of the Fourth Crucis to surround the Capellans. All the Capellan attackers were destroyed in the ensuing firefight.[52]


The Word of Blake (WoB) conquered Basalt in September 3069, incorporating it into the Word of Blake Protectorate[45] and hoarding its mineral wealth for themselves. This resulted in a planetwide economic depression that only started to lighten when the world became part of the Republic of the Sphere.[1]

In 3071, a raid by an unknown mercenary unit attempted to destroy a supposedly unguarded Word of Blake reeducation facility outside Rose City, but then retreated through the city when faced with elements of the Protectorate Militia 'Mechs and tanks. Although the mercenaries were able to reach their DropShip and escape, the Basalt Protectorate Militia was able to stop the mercenaries from causing any significant damage to the facility.[53]

Military Deployment[edit]


Basalt has five continents named Amethyst, Garnet, Opal, Topaz, and Quartz. Basalt is a high-gravity world with a dense atmosphere and wild weather patterns, but is rich in mineral resources.[1]

Planetary Locations[edit]

  • Manville: planetary capital city[1]
  • Rose City: a city home to one of the WoB reeducation centers[53]
