Great. I'm adding things to the Codex every day. Until it's ready, those interested can think about a few things concerning characters. 

The small town in the neutral zone is called Helston. Your character can either be a native or someone who moved there from another place in the neutral zone or one of the unions. I used the term 'young adult' for the protagonists for the sake of a wide range of ages. It could be anything between 18 and 30. The typical 'background' section of the character sheet will be called 'memories', instead, so as to allow for specific events of the past that tells us more about the character.
