The Carse system is located near the Diosd and Galuzzo systems and is dominated by binary stars, one class M1V and one class G1V, orbited by at least four planets. During the thirty-first century recharge stations were in place at both the system nadir and zenith jump points.
The Carse system was colonized at some point during or shortly after the First Exodus from Terra and was a member of the Tamar Pact prior to the formation of the Lyran Commonwealth in the mid-twenty-fourth century.

Carse IV—more commonly known simply as Carse—is the fourth planet in the Carse system.
Carse came to be located on the Lyran Commonwealth/Draconis Combine border, abd was the site of many raids and battles over the course of the Succession Wars. In addition to this, the double sun and Carse's unusual orbit provided four cycles of seasons. During a Cold Cycle (which is what Carse was in during the early part of the thirty-first century) the temperature plummeted, oceans froze, and only DropShips and the largest air vehicles could survive the heavy winds. Fortunately for the economy, the petrochemicals and metal ores in the planet's crust could still be routed to the factories that produced plastics and plastisteel. Most of the Succession Wars-era damage was been confined to areas far away from cities. Due to its proximity to the Combine, Carse also served as a waystation for Lyran traders looking to enter or leave Combine space.
In February 3052 Carse was invaded by Clan Wolf as part of the Fifth Wave of Operation REVIVAL. The Red Keshik, Eleventh Wolf Guards and Thirty-seventh Striker Clusters were opposed primarily by the Second Freemen, although approximately a quarter of the Twenty-third Arcturan Guards RCT had refused to rotate off Carse months before, and fought alongside the Freemen. In a rare strategic mistake the Wolf forces made their initial landing on the wrong continent: whereas the capital city New Bonholm and the majority of the planet's resources and industry were on the norther landmass, the Wolf LZ was on the southern one. This gave the Freemen plenty of time to reconnoiter the Wolves and realize just how hopelessly they were outmatched. Thankfully the planet's constant, frigid storms grounded all aerospace forces, giving the Freemen a fighting chance when they confronted the Wolves at Molde and then at Trosa. While they were able to earn the Clan warriors' respect the Freemen could not prevent them from conquering the world, and the regiment was forced to retreat to Ueda. The forces from the Arcturan Guards who had chosen to stay and fight on Carse—including the Seventy-third Guards Jump Regiment and another regiment from the Arcturan Guards Infantry Brigade—were wiped out, with just a handful escaping either death or being taken as bondsmen.apocryphal) BattleTechnology magazine issue #19 showed a view of the planet. On the inside, the cover caption read, "About the Cover: Although the Steiner Emblem is still clearly visible on this zaibatsu orbiting Carse, the manufacturing facility and the planet it circles have belonged to the Jade Falcons since May 3051."
(It should be noted that this would presumably be a misreporting even if considered canonical, as Carse fell to Clan Wolf, not Clan Jade Falcon.)
