"I am truly sorry to hear that but I understand why you're cautious. We could've planted any type of mass-reproducing virus in those vials and wiped your planet out. Smart move. " William knew the risks of showing them the Enhancements he had but he had to come from a position of power. Not only due to the whole "meet your neighbours" but as well that's what was expected of him. 
Growing up he had to put up with a lot of racism due to his Rejected status but he went up and up in ranks until he Ascended.

"We don't need medicine, that is true. The vial we offered you was a very simple formula our Goddess created in her early days, it's given to our newborns until their bodies are ready for more advanced versions of it. 
Exotic foods? What would you call exotic food? From where I'm standing, everything that's done on a different planet can be named "exotic". Even bread."

William took a deep breath and continued, the same diplomatic smile on his face. More sincere this time than before.

"Your people have also engaged in gene manipulation? Wonderful. I wouldn't be the one allowed to accept this, different branch of the Church for that but, I can certainly say one thing. The Goddess would surely love to meet one of your scientists. I'm sure they would have something to talk about. " 

One of the Elite guards behind William, approached him and whispered to him something. William took another deep breath, whispered something to the guard back and 2 of the guards proceeded to leave the room. 

"I'm really sorry about that, some of the Adepts keep forgetting that there are certain rules that one must follow at all times. Anyways, back to the issue at hand. Natural resources. We currently have a shortage of a certain material, I can send a list of exact specifications on what it is. Maybe your people have it. Nonetheless, I've got something I can go back to the Goddess with and the rest of the Hierarchs. Enough to have a basic treaty in place at least. "

"We have enough space for our people for now. RADX-001 is a big planet, with enough space for everyone. I can say with certainty, immigration for our people is going to cause problems for your people. It's not something I can discuss with an outsider without permission, I'm sure you understand. But, I can make an offer. Have one of your leaders accompanied with one of your scientists and as many soldiers that can fit in a spaceship of yours and bring them to RADX-001 and as I sign of good faith, when your leader goes through the Gateway, I will come on this side. Alone and unarmed.

Do we have a deal? "

An offer like that wasn't supposed to come from William, it wasn't his place to do that but was the best chance for an alliance.
