Eventually, I need to provide a “standard travel time hyperspace table”, or another solution.
Play will begin in the Kamino system, which is at one end of the Rishi Maze hyperspace route. Kamino is a part of Companion (Galaxy) Aurek, a cluster of stars which orbits outside of the main galactic disk. Rishi (the other end of the Rishi Maze) is a part of the Abrion sector.
I expect much of the early game to take place in the Abrion sector and Companion Aurek, though if you wish to hare off elsewhere, we can do that too.
One world within the Cloak of the Sith which is accessible from Rishi, albeit via a circuitous route through hyperspace, is Aquillus
