Xander is the newest to be displaced by Da’ccord. In actuality, he's been pulled into this HOURS before they took the jump to the OuterVerze. Despite this, he's taken it all in his stride, almost as if being thrown into the potential end of all things is somehow better than the life he had before. He hasn't spoken about his backstory at all, leaving it up to interpretation. 

Xander is from a few years into the future, from out standing point. With The God And The Missings, he has been nothing but confident. Being taken to this meeting with Artemis is to show him the scale of the threat they're up against.
