Gordon was the twin brother of Bae Oh, born to Henry Cahill, and Hae In-Oh. Gordon was slightly older, so he became the Ekat leader instead of Bae, to his annoyance. Gordon had the familt copy of Poor Richard's Almanack, and wrote some notes in. He married Lin Kim, and had a child, Alistair Oh. Due to being the only thing stopping him from leading the Ekaterina, Bae had Gordon killed.
