How was Expanse first light constructed?

I get that people are intrigued about the Expanse's future, but I'm amazed that there are more answers about what happens in the future than about the Expanse's history. Fred's videos on how the OPA came to be felt like the best way to learn more about the Expanse.<br><br>I don't want to spark a debate, but I did wonder if anyone was familiar with any other hints as to how the first light was constructed?
