But Half of the Separatist's Military leader's s burly manage to survive "order 66" Ans also they managed to safe half of the droid army form the shout down form the death of the old Separatist's alliance leader's on Mustafa ( you know the lava planet from episode 3 revenge of the Sith) And the Surviving Separatist's military leader's went in hiding for 10 mouth's in the outer rim, rebuilding their force's so they can stand a fighting chance against the Galactic Empire, And so the remain/surviving Separatist's Military leader's spent the last 10 month's in fear, hiding and rebuilding, and hoping that the Empire will not find them. But over the last 10 mouths' of the aftermath of  the end Clone war's .Some how one day one of the imperil Probe Droid's found a active Cis droid factory with active Separatist's droid fleet somewhere in the outer rim.
