Armada Rebellion

The Armada Rebellion was a lamentable event in the history of the Crimson Sentinels Space Marine Chapter between the Imperial worlds of Dermanus Primus and Dermanus Secundus. Long standing rivalry finally erupted into open hostilities, which resulted in a system-wide rebellion that had to be put down by the Crimson Sentinels, resulting in the death of millions of innocents caught in the crossfire.

History
In 652.M34 tension was already high between Dermanus Primus and Secundus after being cut off between the Emground System and the rest of the Imperium of Man. The Highborn of the Hive World of Secundus were outrage as their riches were quickly dwindling and there trading cut off from the rest of the Imperium, and took these outrages to the High Lord of the Hive World, Armada Incarus VII, and he would answer with war. He would send the Highborn into an uproar against the Crimson Sentinels. Where Andreas was seen as a fair and just ruler over Primus and Tertium, Armada was ruthless and unforgiving.

Armada summoned upon his personal armies and the armies of the Highborn, forming a militia to stage massive rebellion against the isolation decreed by the Crimson Sentinels. War broke out between the two factions, greatly favoring the Space Marines and their far greater numbers and equipment. It was a long and bloody rebellion.
