Ars Technica:

The Expanse series takes place two centuries from now in the Belt, a ring of asteroids that orbit the Sun between Mars and Jupiter. People who have migrated to the Belt come from all over Earth speaking dozens of languages, and they’re often isolated for years at a time on remote mining stations. To communicate, they evolve a creole called Belter, which becomes the lingua franca for what is essentially the solar system’s new proletariat. The problem? In the book, Belter could be referenced. But now that The Expanse was coming to television, people would actually have to speak the damn thing. SyFy suddenly needed a linguist who could build a language out of dozens of parts. Luckily, Franck knew a guy. He soon recommended Farmer, who delivered a lot more than they bargained for.

I’m really enjoying this show. It started off a little slow but hit its stride about four episodes in.
