The Edge of the Mandalorian Civil War
Since Duchess Satine Kryze was taken control of and launched a planetwide referendum to break away from the Galactic Republic, Mandalore had been plunged into prolonged chaos.
This had originally been a sector where the Neutral Systems Alliance, Separatist forces, and Galactic Republic forces contended with one another. After Mandalore's reckless referendum lost all credibility, it led to the collapse of the Neutral Systems Alliance, making matters even more complicated. Then, with the defeat of the Confederacy of Independent Systems, the balance of power in this sector became an even greater mess.
Mandalore alone had gone through the rule of former Prime Minister Almec after Duke Satine Kryze vanished, then the rule of Death Watch's Pre Vizsla, and finally the period when Pre Vizsla compromised and appointed Bo-Katan Kryze as Duchess of Mandalore.
The complicated regimes, conflicting interests, and tangled allegiances made it impossible even for the Galactic Empire to grasp the situation in the Mandalore star sector, so it chose to wait and watch.
Besides Mandalore itself, the current Mandalore star sector contained the 1,500 systems of the former Neutral Systems Alliance, remnant Separatist forces, Republic loyalist planets loyal to the Galactic Republic, Imperial loyalist planets loyal to the Galactic Empire, strictly neutral planets, Sefrans Tann's fleet, and the remnants of the Galactic Republic's Second Systems Army fleet.
That long list of headache-inducing factions was the best explanation for the Mandalore star sector's current chaos.
Moreover, the relationships between those factions were anything but fixed. Those planets that proclaimed themselves neutral, for example, would follow whoever offered them benefits.
So there was simply no way to unite such a place in a short time.
Sefrans Tann also maintained a fleet here. She occupied Akiva, a former Confederacy of Independent Systems industrial base
