Editing Reasonable Marines (section)

===Xenos===

;[[Eldar]]: As with all other forces of the Imperium, the Reasonable Marines are naturally distrustful of the Eldar. However, the Chapter has come to accept that it is very possible the Eldar possess knowledge and foresight of events that they do not, and as such give them a bit more leeway and take heed of their warnings. However, the Reasonable Marines refuse to be used as unwitting pawns and do not hesitate to bring force into the equation if there is evidence that they are being treated as an expendable asset (as the Eldar often do when they deal with 'lesser' races). While they generally apply the same ethics they treat all other races with, the Reasonable Marines have often resorted to abducting and taking Farseers, Warlocks, or Autarchs hostage to make it clear that they will not be used. Curiously however, The Reasonable Marines claim three Exodite worlds as their own, having come under their protection after the craftworld Biel-tan abandoned them to an Emperor's Children warfleet which was eventually repelled by the combined efforts of the Exodites and the Reasonable Marines. Having come to a rapport with the Exodites, the Reasonable Marines called in a few of the exceedingly rare favours the Ordo Xenos owed them. To date these three worlds, Lotharis, Galadrian, and Maeveriat are the only sanctioned Xenos worlds in the entire Imperium, even if knowledge of these worlds are reserved to only a select few outside the chapter's borders. The Marines make use of the Exodites by having them teach additional skills to their Apothecaries and Librarians, the Eldar agree to this for their own safety, ensuring that their new protectors suffer fewer casualties and remain uncorrupted by Chaos. It is a symbiotic relationship that has served both peoples well. Additionally, Exodite items are very popular when trading with the Tau. They have extremely friendly relations with Ynnari.

;[[Orks]]: The Orks are beyond reason and beyond even the most basic forms of negotiation. As such, the Reasonable Marines have excluded them from the ethical approach to warfare they exhibit with other races. However, the more 'kunnin' Orks often give the Marines a challenge in guerrilla warfare and as such dealing with high priority targets like Kommandos are treated with the same sporty enthusiasm they would show when competing with the Raven Guard. 

;[[Tyranids]]: Unlike the Orks, who the Reasonable Marines take a more laid back approach to dealing with, Tyranids are a considered a top-tier threat. No holds barred- shoot to kill. The sole race that the Reasonable Marines will bring out the flamers to use on, the Chapter will pursue the routing of the Tyranids with such dedication that they are willing to side with almost any other foe long enough to flush them out and destroy them. As creatures with heavily advanced senses and innate psyker abilities that defeat much of their stealth, the Tyranids are the only race that the Marines will abandon their traditional doctrine in favor of a separate codex's worth of tactics; designed specifically to eliminate them. 

;[[Tau Empire]]: While the Reasonable Marines refuse to abandon the Imperium and as such have no intention of joining their Empire, the Tau are often a welcome change of pace for the chapter. The Reasonable Marines are quick to aid the Tau in situations that do not concern the Imperium, and in return the Tau Septs generally co-exist peacefully with the chapter. Trade is common between the worlds of the Chapter, and the Tau, and the Marines are willing to humor the Tau diplomats attempts at swaying them towards the Empire, if halfway to keep them from stepping up their attempts and the other half to keep their own diplomacy skills at their peak. This isn't to say the two haven't had their battles, but compared to any other faction these conflicts are often brief shows of force rather than full fledged warfare. The Reasonable Marine's dealings with the Tau do come at a price, often earning them a black mark against them in Imperial Chapters or Regiments in neighboring systems.

;[[Leagues of Votann]]:

: For various reasons the Reasonable Marines only recently encountered the Leagues of Votann (it's a big galaxy).  As one brother-sergeant recalled, they appeared as astartes grown from ratlings, approaching on a [[Hekaton_Land_Fortress|stout, armored vehicle resembling a mining rover encrusted with guns]].  This impression quickly soured when they opened their mouths... "WATS DIS THEN?  MARINES in fookin nambyarse cammefloss?!  Don'cha want yer enemy to see ya when dey fookin die?"  

: This has been the dynamic between the two since.  Whatever merits the leagues might have; their hardiness and determination, their proficiency with technology, etc, is completely squandered by their unique outlook on life.

;[[Dark Eldar]]: It would seem surprising that the Reasonable Marines would employ non-lethal weaponry against many of Commoragh's kabals, but the usage here is for a different reason. The Dark Eldar are perhaps one of the only races the Chapter holds and embraces a hatred towards that would be recognizable amongst the other loyalist chapters. Here, the Reasonable Marines use their non-lethal weaponry, stealth and diplomatic skills to deprive the pirates of the thrills they seek in their realspace raids. It is not uncommon for the Reasonable Marines to swap over to lethal weaponry should the raiders prove particularly aggressive or sport a clear agenda they intend to fulfill, something even the Reasonable Marines don't mind admitting they look forward to on such occasions. 

;[[Necrons]]: For the longest time the marching hordes of Necrons have been another example of shooting first and not even bothering to ask questions later in the Chapter history. However, this changed once news began cropping up that the Blood Angels (a chapter they long since held with some contempt) actually managed to ally with them to fight off Tyranids and then peacefully part afterward. Upon closer examination, it became apparent with time that many Necron forces seemed to be displaying an emergent organization- a civilization, no less. In fact, the disposition and behavior of Necron forces began to vary so wildly the chapter was forced to reevaluate the race as a whole. In fact, the chapter has found occasional allies in the Necrons. Though the Reasonable Marines are grateful for the powerful support, they also study those Necrons whom they do approach, in an effort to discern their motives (no small challenge in its own right) . They are not eager to turn on a valuable ally, but neither will they allow the Imperium to fall to Necron rule, be it through force or politics. Despite this newfound position as a sentient race with rights, in combat the Marines apply full lethal force against them. This is largely due to the Necrons unique physiology, whom seem fully incapable of registering pain, let alone truly die. Currently the chapter has found an oddly steady relationship with several of the larger dynasties, where their techmarines (whose science is unhindered by the dogma of the Imperial cult) have collaborated with the Necrons to study potential cures for the flayer virus and the symptoms of dementia overtaking the eldest members. Already under heavy scrutiny by the Inquisition, this partnership is kept top secret even amongst the initiates of the Reasonable Marines, and even the senior officers are aware of the thin ice such an alliance skates.
