See, that's exactly what the realms around the Zuma have been trying to do - figure out how they roll. In one of the older threads when Terran and Co. were grumbling how hard it was to deal with the Zuma, it was said that 'talk to Garrett, he's the Ambassador, the Zuma don't like dealing with human realms directly'. So people started talking to Garrett. Now people are saying 'Garrett is useless, you should have talked to the Zuma directly' - that's where it gets frustrating.
That's just part of the process of figuring things out
If you want a step-by-step walkthrough, there isn't one. If you talked a lot with Garrett, you could have come to eventually realize he wasn't always the best way to approach the Zuma. He was great for some information and he was a good starting point, allowing you to learn a few things about the Zuma without your words pissing off the big bad Daimons. Garrett wasn't the nicest person, but he didn't send Zuma armies towards you whenever you said something wrong (Mostly because he couldn't and was as scared of pissing off the Zuma as others).
