Carnage and Mayhem in Dune

[Khas]

In this scenario, a Guild Heighliner has accidentally opened up a portal to fluidic space, and has successfully pissed off Species 8472.

Meanwhile, on some backwater planet, black and green monoliths, buried for millions of years, activate, and the Necrons pop out.

And in a third part of the galaxy, a giant ring flashes to life, and ships come out, aboard which are mysterious people with staffs who say "Hallowed are the Ori".

Now, the Necrons, the Ori, and Species 8472 have turned the Dune Milky Way into their playground. How does this go?

The Beni gesserit and Guild navigators all have collective seizures when their precog shows them the sheer anount of pwnage that will be visited on them.

I mean do they even have a space navy?

Well, it's known that they can at least nuke a planet from orbit. Other than that...
It could really be a bad day for Dune. Not sure if precog can cope for the addition of a new layer of reality there...
Thankfully, Herbert wasn't much into space battles, and even the info on ground units is scarce. Now, the canon or non-canon books that get penned by KJA under the son's supervision do provide much more action, but they cover periods far before and far after the Paul Atreides era. But there could be a book crammed into that era as well.

I don't think Dune is powerless though, but there's too much speculation to think of here.
Man-protectingHoltzman shields that become nukes if shot at by lasguns opens obvious avenues for space warfare.
Planet burners that can either behave as nukes or drill into a planet and blow it apart also are something else. One can wonder how it really works...
If it needs gravity in some way, it's pointless.
But it only reacts because it triggers something that reacts with the planet's matter, then throwing one into fluidic space could be terrific. Heck, just one might suffice, since we don't know the extent of the chain reaction safe that it stops where the planet ends. Fluidic space could be considered just a vast ocean for all we know.

Chain reaction with planetary mass seems unlikely, as the yield of the stone burner is pre-determined: http://dune.wikia.com/wiki/Stone_burner

new layer of reality? one thing about precog in comic debates we have a good saying regarding precog when the opposition has such ermm advantages? as to make the outcome so brutal and that's

"precog sucks in this case because it's gonna tell the user exactly how badly his but is gonna get whooped"

Herbet was like a liberal version of CS Lewis..in terms of the preachyness of his book but it was really fantastic..KJA's EU on the other hand is..well pretty craptastic according to allot of Dune purists I enjoyed the stories I read when I read them back in HS but you definitely tell the quality was inferior

but as far as I know officially their canon though didn't the guild make sure any space based warfare was a no no ?

would it have the same effect if it came in contact with 8472's anime Chi guns? or the necrons weaponry?

really? I don't remember these

seems a bit stretchy tbh but damn the possibility there is scary

to be fair the original home world of the Corrino family was said to be ravaged by orbital bombardment and just surviving on it ten thousand years later makes for rambo like super soldiers.

they seem to have the ability to make a planet into a wreck of a space rock but to a certain extent that might be limited

Paul remained silent, thinking what this weapon implied. Too much fuel in it
and it'd cut its way into the planet's core. Dune's molten level lay deep, but
the more dangerous for that. Such pressures released and out of control might
split a planet, scattering lifeless bits and pieces through space.

Teknomadjick.
It seems the reaction reaches a whole new level when it can be initiated with the fires of a planet's guts.
So, in fluidic space, it may be too cold to get there.

Well, none of the intruders have shown the will to talk. 8472 kill because of some racial bias, Necrons... they won't sense Chaos or even WH40K humans, since Dune humans are all pure pariahs, just like any human in any other universe so they may decide to return to sleep and call it a (wonderful) day (as long as they don't eat a star) and the Ori... those are going to be a problem.
The Guild is going to hate them all for they break their monopole on FTL travel.
We know what a can't take down an Ori ship: a concentrated geyser of nuclear fire poured through a stargate, resulting from the complete vaporization of a 11 km hiveship next to the stargate of departure. With stargates capable of channeling multi-gigaton blasts easily (and we're talking about two to three digits here), all we can safely assume is that it takes blowing up a planet in front of Crusaders in orbit to blow them up, and that they can at least tank something like 26 megatons and perhaps much much more (again, looking at what that tincan of Destiny could do in regards to blue giants, there are chances that 26 MT is a damn low end here, especially since Goa'uld, Asgards and Tau'ri weapons are known to easily achieve multi-megaton yields and even up the gigaton range). However, I'm not sure about the vortex that brought them here, and it's possible that they won't sense the Ori anymore. Like very preachy zealots, the first thing they'll think is that they have sinned some way or another, and will probably do all that is possible to get their gods talk to them once again. Which means we may have even more absolutist Priors on our hands than ever.

I can easily see that turn into a match between the Ori and 8472. In fact, with the Ori wanting followers and 8472 wanting to kill them all, the Priors will do their best to protect all humans. It all depends on when the 8472 attack and get known to the Ori, because before that moment, the Ori will menace human populations.

but as far as I know officially their canon though didn't the guild make sure any space based warfare was a no no ?

They essentially maintain their grip by forbidding any kind of space and orbital warfare, including the use of atomics. Otherwise, a planet gets punished. Now, when you control space, it doesn't take much power to punish a planet, even with mere nukes.

would it have the same effect if it came in contact with 8472's anime Chi guns? or the necrons weaponry?

Hard to tell. 8472 use funky particles, and the main Necron infantry guns cut molecules and suck them.
However, their ships use stars' plasma, which is very luminous, so it could easily result into the destruction of the Dune ships if they use similar shields.

Actually, the Necrons want to purge the galaxy of life to feed their C'Tan masters life energy or souls. The fact that they even exterminate a planet's microbes show just how far they're willing to go.

As for 8472's weaponry, Star Trek Online says that they use antiproton weapons.

Not like those seen in say Star Wars or Star Trek. Each of the Great Houses as well as the minor ones of the Landsraad have their own space fleets, which include such ships as frigates, crushers, dump boxes, monitors, troop ships, and lighters. However, in the time of Paul Atreides and the original Dune novel, none of those ships were equipped with the ability to travel vast interstellar distances on their own. They needed a Guild Heighliner for that. So most of the major powers listed here would run circles around the isolated planetary fleets.

The only real issue here is where do the Thinking Machines and their Synchronized Worlds Empire fit into all of this? They are still out there.

The Thinking Machines under Omnius would love to meet up with the Necrons.
