From the introduction:
In this place, wealth and power are all that matters. The governments of old are gone or rendered inconsequential, with vast, ruthless megacorps holding all true power. Larger than even the greatest nations on Earth, these corporate behemoths seek to expand their power and influence through any means necessary, from fielding their own private armies to hiring mercenaries for more dangerous - and profitable - operations.
You are one of these mercenaries. Your name and background are irrelevant - all that matters is what you do.
All that matters is that you fly the Raptor .
