Can someone explain to me... (spoilers)
...how on Earth the protagonist found the entrance to the lab?
He rides on horseback in a seemingly random direction, and finds a techie who tells him he has no chance against the gunslinger. He replies he does have a chance, like he's got a plan, and follows a river and finds himself in Romeworld. He then gets off horseback and runs, seemingly aimlessly, through various areas until just happening upon some sort of covered well. He pulls the cover off and descends the ladder.
It's ridiculous that he got there by chance, instead it seems like he knew exactly where he was going, but there's no explanation as to why. I had two theories - either he was a former employee of some kind, or the briefing contained some kind of "go here in case of emergency" bit. Neither of these seem very likely, but I can't believe for a second he ran precisely there by accident. What gives?
