This sounds like an interesting idea! I like the title (the final "E" is a little bit cheesy, but it still works). The design for Chén looks great, too.
Moving on to the story.
Typo: you "pore" over a document, not "pour".
Apart from that, I like this. It manages to transmit quite a lot of detail about the world in a short time, and without being info-dumpy. I got quite a good feel for the characters, and I quite like Geraghty, despite his racism. It's a bit dialogue-heavy, but that works for this kind of scene. Definitely seems like it could make an interesting novel.
