The Expanse follows the case of a missing girl whose disappearance brings together a diverse and disparate group of characters in a race to uncover a conspiracy never seen before in human history. Oh, and it takes place hundreds of years in the future. That all said, this gallery will give you the who's who that you need to know.
First up is Julie Mao. She's the aforementioned missing girl. She's an heiress whose political sympathies lie with the disenfranched residents of the Asteroid Belt.
