Coruscant
The next day, it had taken some work in order to find out what happened to the women and kids from the night before. Having been taken first to a morgue for autopsy and analysis, they were dispersed to several funderal homes, as no one facility would have been able to handle them all.
Thankfully, this worked in the favor of you and the Captain; paying for all of that in one, anonymously would have been uncharacteristically generous and possibly brought the wrong kind of attention. Taking care of it in this dispersed way allowed for a greater sense of plausible deniability.
The last one you visited was also the one with the largest number of bodies; including the Twi'lek girl you had given a shot to in order to ease her passing. As you finished up here, you saw that, true to Master Shroud's prognosis, events had turned the public even further against the First Order. There was a huge gathering of protestors and mourners outside the building. A detail of security forces were watching them from across the street.
Normally, a detail would have put down a protest like this; one would have to wonder if they were ordered not to, or if they just saw attacking people angry about the brutality of the First Order as only further proving the point. Either way, being outside of uniform and with your own work to do, it would probably be best to avoid this and carry on with your true mission; finding a way to get to Dromund Kaas.
Getting a ship would mostly be a matter of nursing the bureaucracy. The problem would be getting there; it was illegal for ship navicomputers to hold coordinates or navigational routes to Dromund Kaas or the other ancient Sith homeworlds. An older, pre-Empire vessel might have the data, as would the Royal Hall of Records. The Imperial Palace, formerly the Jedi Temple could have it as well, although that would be incredibly dangerous to attempt. The right person in the black market may have the information.
The Force could be your guide as well, although you would likely need more training and a stronger affinity to pull that off.
