Yes, I'm familiar with them. Bail is...it's kind of complicated. My sister was raised by him. We didn't meet until we were grown, but now we are close. She speaks very highly of him.
Not sure I should mention Alderaan yet...
Thrawn became a bigger threat after Palpatine's death. He was the only one who could get through the squabbling warlords to present a unified attack. The Empire Reborn, it was called. But he was killed by one of his own men in the end.
Mon Mothma was a great help to both the Rebellion and the new government that came after.
In my time, a peace treaty exists...we don't always agree, but we aren't at each other's throats anymore. We even ended up fighting side by side against a bigger enemy for a while.
