WC Saga has posted some character profiles of various pilots. They're split between twoarticles that then break down each person individually. Each one gets a list of biographical data and several paragraphs of backstory.
For this next few character updates, we like to focus on characters first encountered in the Prologue who will carry over into the main campaign. ...we went back and rendered several characters, Sandman’s flight school classmates, that were briefly mentioned in the Prologue missions and the accompanying e-book. Few of them will move on and make appearances in the main campaign.
