Editing Chapter Master (game) (section)

===Factions that you can interact with through Diplomacy===

*'''[[Imperium of Man|Imperium]]''': The guys with whom you'll be associated most of the time. The Governors will give some good stuff if you'll be helpful to the systems in the sector (stuff like extra Requisition, Licenses for Crusades and Fleet Repair, extra recruiting worlds) and maintain a high reputation with him. Just don't give him Chaos artefacts (especially Daemonic ones), else Heresy explodes everywhere, Chaos Marines will pay a very unfriendly visit to you and a world will turn Daemonic. They are the ones who will be the most grateful if you give them Relics, not the Ecclesiarchy, but they will only pretend to be if you send them lesser Relics from the Adeptus Mechanicus.  
*'''[[Adeptus Mechanicus|Mechanicus]]''': They are the guys who'll give you all the cool stuff like Land Raiders, Termie Armours and things like Skiitari, Tech-Priests and minor relics if you have a high enough reputation with them and offer up something nice in return, like STC Fragments. However, they are rather stingy even when presented with STC Fragments (One STC Fragment will usually get you a single suit of Termie armour and 3 techpriests). Protect Forge Worlds at all costs if you want new stuff from them and new ships for your fleet. Nothing happens if you give them Chaos Artefacts (unless you want to summon Chaos Marines this way).
*'''[[Ecclesiarchy]]''': [[Sisters of Battle]] in other words. If you get high reputation with them, then they'll not only send you their own troops when you buy from them, but in certain situations they'll even build a monastery on your homeworld. The sisters will trade you some really useful wargear like Heavy Flamers. Never give them Chaos or Daemonic (especially the latter one) Artefacts, else your reputation will plummet down. 
[[File:Inquisitorial Inspections.png|500px|thumbnail|right|It's something like this with the =][=. And it gets better.]]
*'''[[Inquisition]]''': They hate you. Even with really high reputation, they'll give you missions that will make you RAGE incoherently. Luckily it's not all of the time they do so. Most of the time they'll ask you if you could look after a relic they'll send you. Other times they'll call to blow up Necron Tomb Worlds that are still dormant or kill a Radical (always take the Relic they offer, and then blow up their ships). If you'll have bad reputation with them, then they'll simply excommunicate you and make your life ''very difficult''. Some of the things they give you aren't worth taking, unless those are Crusaders and EXTERMINATUS (the Incinerator is also somewhat good if not only for its bonus against Daemons). They'll be massively disappointed if you trade with Eldar or other Xenos. Their hatred for you is so great that if half the sector is already being invaded by the Orks, and that you are the only one even trying to do something about it (like, sending your entire fleet and a Golden Age Slaughtership to deepstrike at the heart of Orkish territory where they have [[Anal circumference||26 battleships]]), they will still find the time to threaten you about your geneseed incubators (you know, what is needed to actually cultivate geneseeds and increase [[Games Workshop]] sales...) and having executed governors in world that are already lost to the enemy. They're also the only faction that is happy if you give them Chaos Artefacts (especially Daemonic ones). To submit a planet to Exterminatus will cause the Inquisition to be absolutely furious, but to do Exterminatus on a daemon world will get you popular with both the Inquisition and the Ecclesiarchy. 
*'''[[Eldar]]''': They hate you too, but are also attracted to you (especially if the [[Farseer]] in charge of the [[Craftworld]] is female). They'll always mind their own business and will never, ever attack you unless you provoke them. Have some nifty things to sell and will tell you if any of your battle brothers are corrupted or not. Sometimes they'll ask you for some requisition. Word of advice: do it! This way you'll have some peace and quiet, but don't interact with them too often. The Inquisition will make an inspection and overall reputation with the Imperium will drop. <del>Marginally, but it will drop</del> Scratch that. Don't even interact with them if you want to be 100% loyal. Massive trust drop. Their fleet is much more powerful than yours, so never engage them in Fleet Battles.
*'''[[Ork]]s''': Kill them. KILL THEM WITH FIRE! There is absolutely no reason to negotiate with Orks. They'll attack Imperial planets and slaughter citizens. Big pain in the power arse if it's the Forge World next to your home system, or your home system. They can also be very difficult to dislodge from systems with multiple planets, as they spread quite easily within Planetary Systems. Don't bother engaging Ork Fleets, unless they're really small; Ork fleets almost entirely consist of nothing but Battleships, though, thankfully, they don't stay around long - when they reach another system, they'll reduce to minimal size as the ships crash onto the planets in that sector. In terms of Ground Forces, they're usually quite easy to deal with - In the typical Orky fashion, they barely ever hit with their ranged weapons, unless they're either firing at point-blank range, or it's stuff like Rokkits and Kannons. Once they get into melee range, though, they can dish out a fair bit of damage, although they're still outmatched by your regular Space Marines. Thankfully, really 'urty stuff like Power Klaws are too slow to hit anything other than vehicles and walkers. Don't bother attacking/raiding when they have above a Heavy presence level; just bombard them from orbit and clean up with your ground forces afterward. Every now and then, a Warboss will show up to take all the orks in the sector on a WAAAGH! All ork fleets in the sector will double in size, travel to the nearest un-infested system and start fucking shit up, instantly gaining Rampant levels on at least one planet in that system. A WAAAGH! coming from outside your sector is EVEN WORSE; MASSIVE Ork Fleets will appear on a random edge of your sector, and will quite often invade multiple systems at once. It usually takes a lot of time and effort to clear out all the systems invaded by an out-of-sector WAAAGH!, which can lead to you having to neglect problems elsewhere in the sector. 
*'''[[Tau]]''': Just like Orks, Tau shouldn't be negotiated with; they will ruin perfectly functioning Imperial worlds with their Greater Good philosophy and don't give you anything useful. Wipe out the PDF on Imperial worlds they claimed and surgically start purging them. Their fleets are slow and inferior in terms of firepower. The ground forces however, are virtually unassailable. Never engage Tau Ground forces unless you want to take massive casualties; it's much easier to just destroy Tau fleets in space, or just bombard them into the dust if they get a foothold on any planets. alternatively you can send a commando team to "decapitate" them. at which point all their technology and manpower will be yours to do with as you please. make of that what you will.
*'''[[Chaos]]''': As if the two above factions weren't already a pain, these guys will instead corrupt worlds and probably turn one into a Daemon World if they get the chance. They start out as small heretical uprisings on a single planet, but then jizz into full-blown Incursions, with Chaos Fleets popping out of nowhere (Usually near the Forge World that's next to your home system or RIGHT ON TOP OF your home system!), and ending with Chaos Marines and Daemons running rampant. No info on what they would offer. To start with, why would anyone even try to talk to them? Unless by talking, one means BOLTER ROUND TO THE FACE. Stamp out Heretical uprisings as early as possible; in the early stages, all you'll have to contend with is Cultists, who are hilariously easy to kill and have next-to-no chance of even wounding a Marine. Watch out for Arch-Heretics though; the plasma pistols/power weapons they are equipped with can kill marines with reasonable ease if they get into range, but they're just as squishy as a regular cultist. After you're done stamping out any Traitor presence, don't forget to purge to bring the Heresy down to 0%, otherwise they'll just keep popping back up. (Always do a Selective Purge unless the Heresy level is particularly high - that way you minimise the negative effect to the Governor's Disposition). If a planet becomes a Daemon World, do not panic... not all of them can actually produce ships, [[Failbaddon|most of the time in fact they can't]], as long as you have positive 40 points in Disposition, the Inquisition will consent to sell you [[Exterminatus]] devices. To use them, equip one of your marine with an Exterminatus device (probably the 1st Company Champion or another tough as nail warrior like him), play some grimdark music, [[Grey Knight|attack the daemon world]], and as long as you win the battle and that your marine equipped with the Exterminatus device and then watch as they burn, while the Inquisition and Ministorum's trust increase en masse. Or not. Daemon Worlds are very useful to farm experience.
