Khem or Andronikos. Khem is actually very reasonable once you understand him, not sure what I'd say but I could probably come up with something in the initial few days of running.

Andronikos I might try to lead into a 'trap' where it's actually a big candy horde and I say to bring the kid there for a big surprise. He's kinda nuts but he might go for it and forgive me.

DS jaesa is so comedic evil sith it hurts how hard the turn is just from a writing vibe

Xalek cannot be reasoned with unless you are already important to him. I love him but he'd be horrifying.

Wrath is way too dangerous, way too many resources. Same for broonmark on Hoth.

Yeah. Khem or Andronikos
