> Tengu are being all territorial, right? Hopefully Suika has them under control by now, since here's what we can do:
> Convince the tengu that expansion is in their best interests, that building a second power base spreads their assets and makes them less vulnerable to attack.
> Further, tell them that the Underground youkai community are desperate for allies, and that they would do anything to ally with the tengu.
> Obviously, to secure such an alliance, an embassy would be required, and what's the best ambassador than a mighty oni to show the Undergrounders the tengu's superiority?
> Upon arrival, the ambassador hears about a landshark plaguing the Undergrounders' territory, and, being her gracious self, drives the shark out. The Undergrounders are grateful and agree to a treaty that's favourable to the tengu.
> None of this "unfavourable treaty" stuff is actually true, except for the ambassador wrestling a shark. Although making some sort of agreement is really welcome, need to band together and all that.
> Share plan with Yamame.
> [edit] This plan hinges on the hope that the tengu won't ever actually leave their territory to confirm what's going on with the Underground. This seems reasonable, as long as their leaders have them convinced that everything's going smoothly.
