X:Y Coordinates 100.031 : 429.051[e]

The Constance system was home to at least one habitable world or construct and as at 3145 was located in the Rasalhague Province of the Rasalhague Dominion.[1][2]

System Description[edit]

The Constance system is located near the Glabach and Jarett systems.[3]

Planetary History[edit]

Age of War[edit]

The Constance system was colonised at some point prior to the end of the Reunification War.[4]

Star League[edit]

During the final years of the Star League, Constance was the host to a Star League Defense Force garrison.[5]

Clan Invasion[edit]

In April 3050 Constance was attacked by Clan Ghost Bear during the First Wave of Operation REVIVAL. The 68th Striker Cluster was tasked with conquering the planet, then defended by the Honor Guard, a garrison force of five BattleMech companies and two regiments of armor. With major confrontations taking place at Cedar Groves and Harmond Hills, the defenders used every trick in the book to defeat the Clan invaders in this savage battle, including poisoning the general water supply on the assumption the Ghost Bears did not have their own reserves. Star Colonel Chou Vong labeled the Honor Guard dezgra after this incident and used it as an excuse to call down his entire Cluster to finish the battle quickly. However the Honor Guard's use of guerrilla tactics denied this swift victory as both sides resorted to ambushes and other devious tactics. The Honor Guard's elite armor regiments were finally hunted down over the course of five days of attrition fighting.[6]

The Jihad[edit]

In March 3076 Constance was the second of four Ghost Bear Dominion worlds to be raided by Clan Ice Hellion stragglers after the failed Ice Hellion invasion of the Clan Jade Falcon Occupation Zone several years before.[7][8]

Dark Age[edit]

Constance was the site of the Vacaville Slaughter in November 3120 when a group of rebels seized the capital and a Trinary from the 56th PGC was dispatched to crush the revolt. This was accomplished when a Vulture Nova, pursuing the rebels into the Vacaville subdivision, finally resorted to bombarding the entire town. The majority of the civilian population was killed; only afterwards were the rebels found to have committed mass suicide beforehand.[9]
