Lore:
Chrysor was built upon war. In the early 23rd millennium, a human colony ship touched down on the 2nd planet from the local star, finding a comfortable terrestrial world that could support human life without terraforming and naming it Suleika. However, unbeknownst to them, another race of sapient creatures was already inhabiting this solar system and would not permit their territory to be intruded upon. The Kharsenites, natives of the moon that would later be known as Regaeses, were a race of naturally armored, ten-legged aliens that had developed interplanetary travel a millennium prior and formed underground settlements across most of the planetoids in Chrysor prior to human contact. Though Suleika had no Kharsenite inhabitants, it was considered to be within the Xenos' claimed region of space and viewed the humans as invaders to be eliminated.
The ensuing war lasted nearly five centuries and left much of Chrysor devastated. By the end, Suleika was reduced to a mostly desert world, several planets and moons were reduced to cosmic dust, dozens of billions of humans had died in battle, and the Kharsenite race was driven to extinction. After the long and bloody struggle, the colonists were at last able to enjoy a peace that would, unbeknownst to them, not last long.
Scant centuries after the eradication of the Kharsenites, the Cybernetic Revolt tore the human race apart. Chrysor was partially spared this ruination due to having lacked access to Abominable Intelligences, but they nonetheless remained a target for the dreaded Men of Iron. Fortunately for the colonists, generation after generation of brutal warfare had unknowingly prepared them for the coming disaster. Once again, Chrysor was ablaze with the fires of war, and once again, it would be centuries before peace would reign.
And once again, it was not to last. Ever an uneasy voyage, the majority of the whole sector was rendered virtually unreachable as Warp Storms ravaged the galaxy in the prelude to the Eldar's doom. Thus began the Age of Strife. For five thousand years, the humans of the Chrysor system were left to face the horrors of the galaxy alone. Orks, Eldar, Khrave, maddened psykers, and more would wreak destruction upon the weakened human civilization there, though always at an unexpectedly heavy cost. Nonetheless, the unending strain took its toll, dragging the descendants of the colonists to their lowest point ever since their ancestors' original arrival in M23. By M30, only three celestial bodies and thirteen major space stations remained inhabited by mankind, the rest having been abandoned due to a crippled industrial base making their continued maintenance and protection impossible. Most of the system now belonged to Xenos, mutants, and the horrors of the Warp.
When the Great Crusade at last reached Chrysor, it found a human civilization at the end of its rope, surrounded on all sides by enemies and only surviving by a combination of grim resolve, spite, obligation, and blood. Though the knowledge of which Primarch presided over the campaign of reclamation has been lost to time, what is known is that the Imperium was welcomed with open arms, and the Legiones Astartes were celebrated as heroes. However, while all were grateful for the Emperor's chosen bringing light in Chrysor's darkest hour, some felt an unusual anticipation. The history of the system, though heavily mythologized even then, made one thing clear: peace was fleeting thing, and fleet it did.
From the beginning of the Horus Heresy until the last years of the Scouring, Chrysor was once again under assault from raiders and would-be conquerors. This time, however, they had allies. Loyal Astartes, Knights, Titans, Imperial Guard, Navy, and PDF fought together across the sector and proved to be no easy prey for those that would seek to take advantage of the Imperium's recent civil war. This same tale would be repeated innumerable times in the millennia to come, for war would always return.
