View source for Fourth Quadrant rebellion

The '''Fourth Quadrant rebellion''' was a series of wars and rebellions that engulfed a quarter of [[Segmentum Solar]]. The exact dates are not known, but it definitely took place between 775.[[M41]] and 780.M41. The individual conflicts had no single cause, rather countless grievances fostered over centuries of brutality and misrule by corrupt Imperial commanders. Opportunistic [[Chaos]] [[Chaos Cult|cults]], renegades and [[Xenos]] took advantage of the anarchy and over a dozen [[Space Marine]] [[Chapters]] were involved in the fighting.{{Fn|1a}}{{Fn|1b}}

==History==
===Fortress of Kaligar===
The [[Dark Angels]] Chapter was one of four that played the most significant role in crushing the rebellion, deploying in full Chapter strength.{{Fn|1b}} [[Sammael]], [[Ravenwing|Master of the Ravenwing]] assaulted the [[Fortress of Kaligar]] and dueled the eponymous traitor for a full day and night before running him into the ground. [[Kaligar]] transpired to be a member of the [[Fallen]].{{Fn|2}}

===Egammonon Revolt===
The Dark Angels fought in this battle, fielding at least one [[Rhino]] with [[Codex]]-pattern tundra camouflage.{{Fn|3a}} The [[Raptors Chapter]] were also involved, fielding a [[Land Raider Proteus]] with temperate winter camouflage.{{Fn|3b}}

===Storm Marches===
The [[Storm Marches]] were an area of the [[Fourth Quadrant]] dominated by [[Khorne]]-worshipping drift pirates. The Raptors Chapter fought in this region during the rebellion.{{Fn|1b}}

===Sulsalid Campaign - 775-777.M41===
The Sulsalid Campaign was prosecuted by the Raptors Chapter in conjunction with elite squadrons of [[Battlefleet Solar]]. During the rebellion the worlds of the [[Sulsalid Sub-sector]] had deposed their rightful rulers in favour of heretical ideals of 'progress' and 'democracy'. Determined to stop the spread of treachery the Adeptus Terra ordered the swift destruction of the rebellion.{{Fn|1b}}

The Raptors took command of retreating [[Imperial Guard]] forces and used them as cover to launch their own strikes on the enemy control and supply structure. Before long the power-distribution network of the sub-sector's capital world [[Auranar]] was severed in a dozen locations. The rebels retreated before the Imperial Guard's mass assault and [[Assault Squads]] and [[Thunderhawks]] of the Raptors slew the [[Sulsalid Ordinators]] in their sky-palaces, efficiently ending the rebellion.{{Fn|1b}}

===Lycanthos Drift Campaign - 780.M41===
In the closing stages of the rebellion one of the last remaining rebel strongholds was situated in the [[Lycanthos System]], to the galactic south of the [[The Maelstrom|Maelstrom Zone]]. The [[Astral Claws]] [[Chapter Master]] [[Lugft Huron]] was elected battle leader of a force comprising Space Marines from his own Chapter, the [[Fire Hawks]], the [[White Scars]] and the [[Celestial Guard]], as well as [[Death Korps of Krieg|Krieg]] and [[Kol-Sec]] Imperial Guard and the [[Imperial Titans|Titans]] of [[Legio Venator]].{{Fn|1a}}

Under Huron's leadership the system was purged in under a year. Huron himself led the assault on the 'widowmaker' bastion gate on [[Lycanthos Secundus]] - an almost indestructible fortress garrisoned by the [[Bleak Brotherhood]] [[Chaos Space Marines]].{{Fn|1a}}
