[Dune] What would happen if a minor house discovered FTL technology?

Would the Emperor seek to destroy them?

FTL technology isn't a secret. What the Houses lack is the ability to travel safely. The Spacing Guild has a natural monopoly on FTL travel only because they spent generations breeding navigators using Spice. The threat of losing access to space travel is enough to prevent any House from making the attempt, but that would also take hundreds of years to accomplish. It took the Bene Gesserit 10,000 years to breed Paul who had the ability to see the future and make safe jumps.

Towards the end the Spacing Guild loses their monopoly to Ixian No Ships, but they were still powerful.
