GAME OVER!
You're a merc - you've been a merc for years. Now you've been offered a job that looks like a milk run. You're a little suspicious because the pay is good. Real good. So good that you take the job because you need the money, knowing all along that you'll regret this decision. But you've been between a rock and a hard place before. The problem is, nobody's been between ComStar and the Word of Blake before. No amount of money is worth that.
