I think I have a idea of what might happen in the next dune books that ties into all the previous dune series..legends of dune, prelude to dune and the original dune. Firstly, after Iblis Ginjo is killed, knowledge of the tlulaxas evil activities becomes widespread and the league of nobles comes to destroy their homeworld as described in a piece of writing found on the official dune site. The remaining tlulaxa flee into Machine Territory.

After a series of events they find there way to Erasmus, the enlightened machine. Erasmus expressed desires to create a human from the ground up and with the Tlulaxas intimate knowledge of genetics he is able to do so. Although this isnt normal humans. At this stage perhaps face dancers are a 'secret project', and with erasmus help, his knowledge of human biology, they are able to create the first axolotl tanks. After much experimentation, face dancers are perfected, and through some machine device, the entire persona 'soul' of Ominius and Erasmus are put into these two face dancers. When the end of the jihad is near, and Omnious is near defeat, the two face dancers 'daniel' and 'marty' are sent out into the depths of uncharted space, far beyond the Imperium with a contigent of robots and an Omnius core.

This 'machine scattering' would be similar to the one the GP Omnius created. With the knowledge of the axolotl tanks, the face dancers are able to achieve immortality. Presumably all the traitorous Tlulaxa would be wiped out by the plagues Omnius unleashes and it is other surviving Tlulaxa who later form the Bene Tleilax. This would explain why no one knows of this, even the Bene Gesserit.

Coming onto the prelude of dune, in House Corrino, the amal spice sends the heighliner out of control and sends it far beyond the Imperium. D'murr, the navigator on board mentions that he has to get more spice immeadiately and get out of there because an enemy is coming, an ancient enemy of humanity. Prime Projection: Thinking Machines. Now it is mentioned in passing that only a handful of heighlners ever went missing. Suppose they were captured by the Machines. This would give them access to navigators and to Holtzmann Engines. With this knowledge of the Holtzmann equation and the awesome processing power, the machines could understand the equation that only Norma Cenva is capable of understanding.

After thousands of years, they could have developed the ability to control 'techys' and create the net. And finally to tie in the original dune. The two super face dancers daniel and marty display a striking resemblance to erasmus and omnius. Erasmus loves to experiment with humans, and in the last chapter of C:D he mentions he would like to study another tleilaxu master. The new abilities they possess could have been stolen from the tleilaxu from the god emperors scattering or they could have developed them independantly. Another likeness daniel and marty display to the machines is their obsession with gardening, particularly pruning roses.

Thats my theory on what happens in the next dune. Feel free to comment and criticise.
