That's one of the reasons why, instead of just forcing this rebellion immediately, I took some time to discuss it with Ophidia. So that we could all be on the same page. Less chance of drama and all that, y'know?
The issue I see with this tactic is that, well, it doesn't make IC sense.
The Chiss have, historically, been undermining the One Sith's rule. This ultimately led to the then-Darth Vornskr attempting to murder 800,000,000 Chiss, or ten-percent of their population. An act which Isamu himself stopped.
To me, the logic just doesn't hold to scrutiny. I can't fathom why they would trust, let alone aid, the One Sith. The tyrannical faction that has attempted to inflict a genocide on their people. Especially with aiding them against the faction that stopped said genocide, Isamu and the Iron Empire.
Please don't take this as me arguing, or saying you can't attempt that tactic. I'd just prefer for Ophidia to touch base, and give his thoughts.
