Jaghatai Khan - Relations with other Legions: Jaghatai's closest relationships with his brother Primarchs were with Horus Lupercal of the vaunted Luna Wolves Legion and Magnus the Red of the Thousand Sons. With Horus, the Khan shared a love of the rapid assault, as well as feeling understood and accepted by Horus.This understanding was also only truly shared by Magnus, who, like the Khan, was as much an outsider to the other Primarchs as Jaghatai. The close relationship of the White Scars Primarch to these two brothers was matched, somewhat, by the relationships between their respective Legions.Several White Scars Brotherhoods (companies) would often be seconded to fight alongside their cousins from the Luna Wolves. These Brotherhoods would utilise a mix of both Vth and XVIth Legion tactics, including the latter's more consolidatory approach to rapid warfare and the more standardised manner of the Luna Wolves' military hierarchy.However, for some Chogorians these tactics could be difficult to understand. Similarly, the Thousand Sons were also known to be close to the Vth Legion for many reasons. The love of knowledge of the sons of Prospero, their enjoyment in the subtleties of the universe and each Legion's detachment from the rest of the Imperium would render a fruitful relationship between these two forces of Astartes.In stark contrast, the Vth Legion seemed to have a very poor relationship with many of the other Space Marine Legions, most of all with the Death Guard and their equally mysterious Primarch Mortarion. It was also known that the White Scars did not get along well with the Space Wolves Legion. All Legions had reputations, and some of these overlapped. The Space Wolves were known to boast of theirs as the Emperor's executioners. When the White Scars fought alongside other Imperial forces they were often unfairly judged, due to their use of ritual tribal marks and scars.People automatically assumed that they were savages, and were no better than the barbarous warriors of Leman Russ that hailed from the Death World of Fenris. The White Scars did not wish to be seen as savages, for they constantly strove to achieve the most noble of human pursuits. In addition, the comparison added salt to the wound of the Vth Legion's entrenched estrangement from the Imperium, suggesting how little others took to understand the Chogorians. Though the White Scars were not "executioners" like the Space Wolves or "world eaters" like Angron's berserk XIIth Legion's warriors or "the perfect" Astartes like Fulgrim's Emperor's Children, the White Scars were what they were.They never demanded respect from anyone, and if the other Legions knew nothing of them, then that was their loss, because the White Scars knew about them. The Vth Legion was faster -- they moved faster and they killed faster. Secretly, the White Scars resented the outsiders' disregard greatly, and yet they refused to change their ways or Legion culture.Many Space Marine Chapters have existed for millennia, with those of the First Founding having their roots in the original Legions created to prosecute the conquests of the Emperor's Great Crusade. With histories stretching back into the dawn of the Age of the Imperium, it is perhaps inevitable that Chapters should come to blows, both metaphorically and at times literally.There are many instances of rivalries, and some of outright hostilities. The deep-rooted and mutual antagonism between the Space Wolves and the Dark Angels is well-known, but there are many more examples. One example of such rivalry can be found in the case of the Raven Guard and the White Scars, who have harboured a mutual mistrust dating back centuries.In truth, there may be no single cause of the bad blood between the two present-day Chapters, but the mere mentioning of several battles are sure to raise the ire of Raven Guard and White Scar alike. The Assault on Hive Lin-Mei is one such conﬂict, as is the Last March on the Sapphire Worlds.Most acrimonious of all is Operation Chronos, in which a venerated Raven Guard Chaplain fell to Enslaver domination in circumstances where a nearby White Scars force might have been able to intervene. The ill will created by these and numerous other incidents has led to the two Chapters even in the late 41st Millennium regarding one another with barely-contained loathing, a situation that none can see an end to any time soon.
