Copying in from discord:
Ok. So basically, we make a three-party deal:
The Gouketsu make the pangolins aware that we can make skywalkers, and that we are willing to trade them to the pangolins in exchange for a garunteed-enforceable agreement that they will treat conquered people with respect and make them full pangolin-empire citizens. We also make them aware that in order for such a deal to take place then they need to create a method of binding themselves to honour the agreement (and no, a sense of honour is not enough, "My uncle, who creates the seals, assumes your words mean nothing. He's paranoid like that.").
The Nara are called in to be solicitors and make sure the enforcement method works. The pangolins must pay the Nara clan for each enforcement method they want the Nara clan to test, meaning the Pangolins are incentivised to create a working version first time so as to spend as little as possible. The Nara clan also want to maximise their payout, so they're incentivised to find out if it doesn't work.
At the end of the day, The Gouketsu get a non-horrible seventh path, the Pangolins get military supremacy, and the Nara get a payday. As far as I can see, no one is incentivised to rebel.
Thoughts?
