Which has been halted for many years due to the awe-inspiring psychic powers from the Zoanthropes. The Hive Mind hungers...
Right, self-defense is obvious, I'm talking about a great-scale reasoning and the hopelessness of the lore. The difference between grimdark and doomed grimdark.
Same with Tyranids though - if an army is destroyed, more will be spawned. Besides, when the Daemons do return, the Tyranids would have moved on after devouring Shadowbrink, so there would be nothing except a barren rock for the Daemons to corrupt. Not much of a playground for them...
I hope so - that would be one of the most interesting conclusions. Either the Tyranids devouring everyone or the Necrons building a super laser to destroy Terra and the other Imperial worlds, before turning to the Eldar, Chaos, Orks and other stuff to reclaim their empire.
Their old lore was much better. They stood as a single menacing threat to the entire 40k universe rather than an inconsequential splintered set of forces. Besides, the C'tan were awesome. I was hoping that they would rolled out the remaining two C'tan (the Void Dragon and the Outsider) but instead they reduced them all to shards. I don't accept any Necron fluff that came after this glorious codex:
Oh believe me I get it. I was mainly teasing. Thier interpretation in the commisar Cain book on an ice planet was top notch
To be fair, I had a friend that would literally buy plastic croissants and put necron guns on them for gunships
Seeing as chaos will ultimatly overwhelm everything it is. Chaos as an enemy is an unstoppable inevitble force of nature. They're sooner going to stop the heath-death of the universe than stop chaos in 40K... As for respawning the realm of chaos doesn't care about time, might be a millenium, it might be 1 second.. There's destruction & undeath to be a threat too. Plus, noone says all of order needs to be on friendly terms with eachother all the time. Have the dwarfs and elves fight a cataclysmic war for a while, plenty of story there.... And chaos could be fine as an ever present threat without posing the ever present threat of a freaking apocalypse. A mortal khornate army rampaging throughout the lands and murdering people is plenty of a threat without it also being a herald of the apocalypse. It's the fact that it's an everpresent, and ultimatly unstoppable, threat of apocalypse that just makes it all so pointless. Tyranids, just like any mortal race, can ultimatly be defeated though. Their resources are finite. Defeat enough Tyranid armies and eventually they have no biomass left to spawn more. You won't be able to do that with chaos. Hell even if you'd permanently destroy demons, or even the actual chaos gods, you'd barely make a change given how chaos is the literal embodiment of primal emotions and instincts so they'l be back sooner or later... The only way to destroy chaos is to literally destroy everything else. And before someone goes "but if the tyranid's eat everyone there's nothing for chaos to feed on". Tyranids are still alive, they still exhibit traits like violence or scheming to some degree. It might leave chaos in a much diminished state, but still there. And the further the Tyranids evolve the more these pronounced these traits become ultimatly restoring chaos back to its former glory... Plus as they're living things Nurgle should be completly fine with just Tyranids around... The literall only thing that actually stops chaos is the utter and complete destruction of everything. In which case there isn't anyone left to be a winner... Which isn't so much grimdark as it is just hopeless. Grimdark usually means there's at least a chance of winning for the good guys albeit at high costs...
