Forum:KB:Coruscant underworld during Legacy era

I'm working on the Coruscant Security Force article and I'm tryin to find a source for the following info that was there before I started working on it:

From the CSF article: Though the Coruscant Underworld was still rampant with crime and other effects of the Yuuzhan Vong War as late as 40 ABY, the Galactic Alliance held off on doing much in favor of assisting galactic reconstruction. By the time the Fel Empire took control of Coruscant in 130 ABY after the Sith-Imperial War, the CSF had finally managed to bring security to the Underlevels after many millennia of lawlessness and instability. From the Coruscant underworld article: By the time the Fel Empire took control of Coruscant in 130 ABY, the exotic Yuuzhan Vong wildlife had been cleaned up and security had finally been brought down to the Underlevels after many millennia of lawlessness and instability.

This information is also on the Coruscant article. Since it exists on several articles I'm assuming there was some reason to put it there besides fanon. Does anyone know where this information came from so that it can be sourced?
