I learned much on my trip to Betelgeuse. I made contacts and allies that would be useful in later years, and negotiated trade agreements that helped both our peoples. The Peloran were generous in their own way, but they needed nothing from us. They had no incentive to share one bit more than they wanted to. But the Branan needed the hyperdrive. They were far more advanced than us in most other ways, and they gave us a wealth of technological examples and theories that would have made Einstein cry from joy. Or weep in horror. The technologies I brought back changed our world. It is common knowledge that the Peloran gave us the stars. It is less common knowledge that the Thunderbirds gave us the capability to defend our stars. And when The War came upon us all, they fought with us.
