The bad news is, the situation is probably not heading anywhere good. Firstly, there is a "mafia" at this company. I don't mean it in a negative way, there is always a "mafia." The problem is, you're not in it. The second problem is, they are proceeding in ignorance. The probability they will encounter disaster is significant and there's no reason to think they wouldn't throw you under the bus. Be careful.

The good news is twofold.

"I feel like I played my hand wrong."

Firstly, there's not a lot you could have done, outside of Machiavellian maneuvering. The current situation is mostly the results of choices other people made.

Secondly, it sounds like you've built up your resume there and you're ready to leave. I'd recommend you let go of the past and start thinking about your future and what other opportunities you'd like to pursue.
