Scenario:

The Cylonian Jihad.

A Cylon baseship jumps to Salusa Secundus c. 10,000 A.G. during the reign of Shaddam IV. The Cylons attack enforce against the Sardukar training home planet.

The war begins.

Scenario:

The Cylon forces of Battlestar Galactica
V. The Old Empire of Dune, including aid from the Bene Gesserit, Spacing Guild, the Bene Tleilaxu, and the Landstraad.

The Cylons are ready, willing, and able to use similar tactics to how they annihilated the bulk of humanity. By the time they're reached Salusa Secundus, they've all ready sneak-attacking several other worlds, including Geidi Prime, Corrino, and Caladan.

TO CLARIFY: -Only- Frank Herbert's books count as canon. No prequel references and obviously, no technology from later Dune books than the first.

Do the Ix have null-tech, as seen in the prequels?

No, as that is the most complete bullshit that has ever been written into Dune. It is quite explicitly noted in God-Emperor of Dune that No-Tech was not produced till the last years of Leto II's reign.

Oh good. The prequels are really quite terrible. Did you ever read the penny-arcade about Herbert Jr. sodomizing his father's corpse? An adequate summation of sentiment.

One thing about Dune was how little Herbert spent on describing weapons. The series was always about people, their societies, relationships, politics and other liberal stuff. Nothing about really big guns with jiggawatt flux capacitors that annihilate planets. Not much for geeks to get stiff over.

The people of the Dune universe had already fought a huge war against machines. They are probably pretty good at killing robots. We also know that they have atomics that can destroy planets (the stone burner that blinds Paul could have melted to Dune's core). We know they have very large ships, but no specs on what sort of armaments they carried, if any. An attack on the Guild would be suicide.

The Guild Ships were tremendous, but could they launch a succesful attack against a warship? Specifically warships that also enjoyed space-folding technology, which not only can do long distance jumps, but point jumps?

Also, the Cylons do have the advantage of a near unlimited amount of troops, owing to their ressurection technology. Unless the Dune people figure out that the ressurrection ships are meant for that...

But yes, the stone burners and such are quite good weapons, but would they harm machine eyes? Perhaps they'd burn the organic Cylons, but not the bullet-heads. They could also not really counterattack the Cylons based off planets. After all, the Cylons likely do not need planets aside from mining.

Shields would, however, essentially turn the predominately shell-based weaponary of Battlestar Galactica into useless nonsense. Of course, it only atkes one Cylon raider suiciding into a shielded ship with a nuke...Cylon wakes up five minutes later, no one onboard the Dune ship does.
