SDTCI AU where Luke's New Jedi Order gets sent back to the Clone Wars and does the whole "pretending to be Sith" plot but they're just so...bad at it that the Jedi Order goes from DEFCON 1 at the seeming appearance of all these new Sith to just shrugging and letting them do their own thing.
"So these new Sith are...breaking up slaver rings, protecting refugees, slicing Droid armies and turning them against the Separatists, and generally doing the stuff that the Jedi would be doing if not for this war?" "Well, they have assassinated several high ranking senators and military officers such as Sate Pestage, Hali Burtoni and Wilhuff Tarkin," "I do see why that would be concerning," (But not our problem, they say between the lines). "And they do seem to have allied with Jabba the Hutt," (Note: 'Jabba' is this case means Ezra. The the body of the Jabba the rest of the galaxy is thinking of has been shoved into an uninhabited pit in his Palace). "Didn't we just strike a deal with the guy?"
They do send some Jedi to 'investigate' but it just ends with said Jedi having a philosophical conversation with their leader, Darth Vader, his scarier sister Darth Venga and talking about Vader's apprentices and Venga's children, Fel, Caedus, and Shuno. Also there's this one seemingly force-null guy serving tea and talking to a very familiar looking Wookiee.
Merrin and Cal definitely hunt down Grievous. Ventress (and Lyco) and Barriss both definitely hunt down their Clone Wars Era versions into order to wrap them in cotton, Ahsoka starts doing Fulcrum shit just in case, and Celina Marriss and Rinna Sliven (And Celina's children Ben and Shmi), representatives of the new Free Tatooine, start courting more planets to the Council of Neutral Systems.
I feel it eventually ends with Vader being caught during an attempt to kidnap Palpatine, where he regales his captors with a story supposedly taking place long ago in a place far, far away, ending just in time for the bomb Mara put in Palpatine's desk to go off and kill him.
