Here's everything you need to know about DUST ATM:

• The Dust cloning tech we mercs use is not made by New Eden civilizations. It was harvested from within wormholes found in New Eden (the EVE Universe) and applied directly to soldiers. The Amarrians were the first to do this. Their prototype was a Caldarian named Vince. We call him Templar One.
• It came to light that the original owners of this technology, a partially extinct advanced human civilization that lived within the wormholes, still had fragments of their consciousness within the cloning technology. So by harvesting it, we were committing massive genocide.
• Amarr saw this and the Empress Jamyl Sarum decided to eradicate all of the clones she had created. But Templar One escaped to Mordu's Legion.
• The other empires are now creating their own clone-able soldiers for ground wars in New Eden, but there are setbacks. More and more clone soldiers are succumbing to the Sleeper consciousness within the technology in their bodies. This has something to do with the number 514, but we don't know what yet.
• Currently, the Caldari are in a miniature civil war against both protesters of the Provist regime (Tibus Heth's personal lackeys (Tibus Heth runs the Caldari State)) and an unknown number of "insane" clones, such as one who tried to murder him a few weeks ago.

That's the gist of things so far. If you want to know more, you can look here and here.

I would add that the Empress offered all the factions "clean" transfer technology that doesn't use the stolen implants to replace the tainted clones. She did this to avert a disaster, which seems to be coming to fruition in the Caldari State.

We are products of the new tech (Mordu's Legion) so we don't have sleepers in our heads.
