Formed Around 2981

Formed in or around the 2980s, Pi Galaxy was a solid and dependable garrison force within the Clan Homeworlds and was brought to the Inner Sphere just prior to Wave Four of Operation REVIVAL in 3050 to garrison worlds taken. During the first decade of its tenure within the Inner Sphere Pi Galaxy saw relatively little combat, other than attacks from particularly bold pirate forces.[1]

Pi Galaxy was understrength in terms of heavy BattleMechs, something that made it difficult for the Galaxy to achieve the victories that might perhaps be expected of a similar formation; lacking a Bears Regular unit, Pi Galaxy depended on the Twenty-third Provisional Garrison Cluster to act as the Galaxy's main offensive force.[1]

One of the more notable actions Pi Galaxy was involved in following Operation REVIVAL was rebuffing a substantial pirate attack on the world of Thule in September 3060. Defending Thule at the time was the Fifty-fourth Provisional Garrison Cluster, a Cluster noted for acting as a training cadre for warriors freshly deployed from Ghost Bear sibkos. A pirate force almost a full regiment in size appeared at a pirate point within the Thule system that the Ghost Bears were unaware of and launched a heavy attack on the Fifty-fourth, threatening to overwhelm the Cluster. Fortunately for the Fifty-fourth, one of the Star Captains within the Cluster noticed that rather than being a cohesive force, the bandit regiment actually appeared to have been formed from numerous smaller bands. some of whom were actively hostile towards other elements of the formation. That Star Captain was able to broadcast antagonistic messages that prompted some of the pirate sub-units to turn on each other, giving the Fifty-fourth a chance to regroup. The attack was rebuffed, but almost two-thirds of the pirate forces managed to escape.[1]

First Draconis Combine/Ghost Bear War[edit]

Pi Galaxy remained a defensive formation during the First Draconis Combine / Ghost Bear War, but took damage defending the worlds of Jezersko, Porthos and Thule from hostile raids.[2]

The Jihad[edit]

Although Pi Galaxy was a defensive formation, it was added to Alpha Wave during the Ghost Bear campaign against the Word of Blake in the Jihad. Alpha Wave was led by Alpha Galaxy and included Omega Galaxy as well as Pi; Pi acted in support of the other Galaxies and missed the campaign to liberate Kaus Borealis, but joined the second wave of attacks against Dyev.[3]


After landing on Dyev during a wave of attacks against worlds in the Word of Blake Protectorate in July 3076,[4][5] Pi Galaxy found itself facing a Blakist counteroffensive in December when a task force breached the blockade of Ghost Bear and Snow Raven ships in orbit and landed six Divisions of troops on the surface of Dyev. The Blakists landed around Trogport and the planetary capital, Novaya Mensk, before deploying outwards. Pi Galaxy fought alongside Kappa Galaxy against the 32nd Militia Division and the 2nd New Earth and 1st Zosma Protectorate Militia Divisions; the Blakists used the fortifications built in previous years by the Draconis Combine Mustered Soldiery to try and resist the Ghost Bear attack.[6]

Pi Galaxy proved its mettle on Dyev, with the Fifth Phalanx proving particularly adept when dealing with the various fortifications on the planet. The Fifth proved successful enough that the Blakists finally launched attacks using Manei Domini specifically targeting the Fifth, leaving the Cluster decimated.[3] History records that the 32nd Militia Division was subsequently destroyed on Dyev before the end of 3076.[7]


In addition to joining the campaign for Dyev, Pi Galaxy won the honor of liberating the world of Asta.[3] By this point, the Ghost Bears were acting as a part of Operation SCOUR, and as forces from the Draconis Combine led by Tai-shu Isoroku Kurita concentrated on securing the planetary capital, Excaliba, in the face of fierce resistance, before clearing the remainder of the Balerdo continent, Pi Galaxy concentrated on the Moolai continent.[8]

It was from a prison camp on Asta that the noted warrior Andrew Redburn was liberated on the 18th of March 3077;[9] Redburn had provoked a series of uprisings in Blakist reeducation camps beginning in the port city of Logan and then spreading through other camps a week before the Coalition forces arrived. The prisoner uprising distracted the Blakist forces, speeding up the campaign to liberate the world.[8]

The Dark Age[edit]

Pi Galaxy was one of a number of Galaxies to be disbanded by the Dominion Council after the Jihad as the Ghost Bear Dominion began the process of rebuilding its forces. Elements of Pi Galaxy ended up in both Theta[10] and Kappa Galaxies; perhaps most notable was the merging of the Thirteenth Phalanx into the Fifty-fifth Provisional Garrison Cluster within Kappa Galaxy.[11] By 3085 none of the former Clusters from Pi Galaxy remained as discrete units within the Ghost Bear touman.[12]
