[Oh dear. This is where it gets complicated. He pauses, contemplating how to explain this.]

Not just the Grasslanders. The Zexens, too. [Hmm. He would have to back up a little bit.] The Grasslanders and Zexens had been on the verge of war for a long time, and all they needed was a little push to start conflict. That's where the Harmonians come in - they're out to conquer just about everyone. But there was no way the Grasslanders and the Zexens could face Harmonia when they had enough problems going on between them internally. That's where I came in - I had to convince the Grasslanders and Zexens to work together to fight off the Harmonians.
