tyranids on necron held worlds.

[Collossus]

Guys this may be something that was addressed long ago or it may be a stupid question, but I only recently got into the 40k universe and haven’t the luxury of reading any of the novels so my knowledge is limited.

I remember reading something about the hive fleet avoiding worlds with necrons or necron ruins in them (Codex maybe);

I was wondering if this was true and why this would be the case? How would the nids be aware of them?

I am not sure on the number of planets with these ruins, but if it is substantial percentage of all habitable planets in the galaxy dose that automatically mean you are safe from tyranids expanse by locating there?

Why would the nids avoid the necrons anyway? If they cannot get substance from the necrons I am sure there are other resources on the planet that would taste just fine…..

I think most planets with necron ruins are dead or relatively dead- Tyranids wouldn't have much interest in a barren iceball or rockball.

Yes, you are perfectly safe from one horde of life devouring locusts. And all it takes is setting up shop on top of a hive of life devouring locusts.

Why would the nids avoid the necrons anyway? If they cannot get substance from the necrons I am sure there are other resources on the planet that would taste just fine…..

IIRC, necron weapons demolish things on the molecular level. Thus the nids would not only gain nothing from eating them but they would also not regain the bio mass they lost. And once your primary strategy of combat is wrapped around throwing flesh wall after flesh wall at the enemy, each wave made out of the same flesh over and over again... Well you can see how the costs of taking the planet would outweigh the gains.

ANd moving to a Necron held world is a really stupid way to be "safe" from the Tyranids - you'll be safe from the Hive fleets but have to deal with the Necrons instead. One implacable foe for another.

EDIT: Damnit, ninjad

[Simon_Jester]

At least the Necrons are lazier than the Tyranids. You're safe while they're napping.

[Black Admiral]

Plus, at least some Necrons (as seen in Dead Men Walking) will be kind enough to serve an eviction notice before resorting to more direct methods.

[Eternal_Freedom]

True. But they all seem to be waking up now, and the Silent King hs returned to the galaxy once again. Either way, if I had to chose a "safe" haven in the Imperium, I'd pick some enormously fortified bastion like a Segmentum headquarters or something. I'd rather but my safety in the hands of my fellow humans than a race of xenophobic genocidal robo-zombies.

Oh okay, yeah that would definitely help them overlook it. I was under the impression that these worlds had time to rejuvenate and at this point were relatively "normal." I also didn't quite get if they were overlooking the worlds as you said or just actively avoiding them.

[Collossus]

Yes, you are perfectly safe from one horde of life devouring locusts. And all it takes is setting up shop on top of a hive of life devouring locusts.

Well this option would of course only be used in dire situations..... wouldn't you at least take the option the offered some time? even if you didn't quite know the length therein?

The new Necron Codex offered a tasty little snippet with regard to Necron/Tyranid relations.

P.24.

The Silent King enters the bounds of the galaxy once more. Having encountered the Tyranids in the intergalactic voic, he recognises the threat they pose to the Necrons' apotheosis - if the Tyranids devour all life in the galaxy, the Necrons will never find living bodies to house their consciousnesses. Thus does the Silent King break his self-imposed exile with the goal of marshalling his people against this new threat.

However, the Silent King has not anticipated the torpor in which the majority of the Necrons still lie. Many Tomb Worlds have been destroyed over the aeons, others still slumber and most of those that have awoken are still disorientated or somehow damaged. The SIlent King is therefore forced to re-evaluate his plans. Working with the surviving Triarch Praetorians, he begins a pilgrimage across the galaxy, stirring those Tomb Worlds yet to revive, and speeding the recovery of those Tomb Worlds already awake. It is the Silent King's wish that they younger races' flawed attempts to destroy the Tyranids do not simply feed the Hive Fleets beyond the point where even a united Necron people have any hope of victory.

Aside from that, it must also be borne in mind that the Necrons have no Warp presence. The Tyranids are psychic (they probably could not function otherwise), meaning that they might not actually notice Necron Tomb Worlds due to a lack of any meaningful psychic signature. This is not universally the case, as some Tomb Worlds actually have thriving civilizations or colonies inhabiting them (having evolved or arrived since the War in Heaven). In which case it is entirely likely that Tomb Worlds use the same anti-psychic technology as the Cadian pylons to hide themselves.

So the tinheads want to be organic again?

[Vanas]

Further to that, the Necron anti-psyker tech works on the Hive Mind:

[...]In the later years of M41, the Null Field Matrix has proven to have a deleterious effect on Tyranids. The vassals of the Hive Mind are not immune to the unsettling soullessness of the Necrons and the Null Field Matrix only serves to exacerbate this effect on the normally inviolate Hive Mind.

I'd imagine that a Tomb World is basically categorised as 'fuck that' when it comes to Tyranid targeting priorities. Of course, it's still not a good place to *hide*. An active matrix presumably makes a fairly good case for the tomb itself being active.

[Simon_Jester]

The new Necron codex seriously reimagined them- added more complexity to their motives, at the expense of weakening their motives in the eyes of the fans.

It's an open question whether you go with the old or new interpretation, and you might get different answers depending on which codex you prefer to use for source materials.

I happen to love the new necrons and their more complex character. The old necrons lacked character, they were big and scary but the whole point of them being the "y'all are screwed" race waiting in the distance never particularly seemed interesting. My necrons weren't any different from those of anyone else, I may as well have been playing anything for all the personality they had.

I love the new flavors of necron worlds we have in the fluff. I love the idea that the necrons are powerful to the point of near omnipotent manipulation of physics, but their inability to make use of conventional faster than light travel means they just have to be that much smarter than everybody else. Hell they literally use time travel to cheat in war times. They're like the love children of the Daleks and the Time Lords.

The best part of the new fluff in my mind is that it wasn't a total retconn of the older fluff. If we assume that the stuff we see the night bringer and deceiver doing in the fluff as we know it so far as being the actions of powerful shards of the C'Tan controlling a handful of tomb worlds, exercising only fractions of their true power, it doesn't diminish the old near lovecraftian threat of the C'Tan. IMHO it actually accentuates it.

Matt Ward's interpretation of the Space Marines leaves a great deal to be desired, and I don't feel that the new necron codex is especially powerful overall, but I very much approve of his treatment of the fluff. So far as I'm concerned the new necron codex is the better one.

I do applaud the effort GW has put forward to flesh them out and differentiate them from the rest of the 'HAHA you're fucked!' races, I don't think I'm crazy about the direction they've taken them. What first interested me about the Necrons was their mystery. They were a cold and unfeeling race of machines from an age of civilization that is millions of years past that were rising up from their millions of years of hibernation.

It's okay how their roles have been diversified from mindless killing machines, but what I don't like is the ancient egyptian Terminator Goa'uld vibe I'm picking up from them. It kind of cheapens their effect and makes them into something conventional and kind of boring (or rather more so then before).
