Rooftops!
The two of them had taken to the old buildings after Oxman had ‘felt something funny’ coming from the ground. Nat hadn’t felt it, himself, but he also didn’t argue. He could sense stuff Oxman couldn’t, after all. And since neither of them wanted to stay out in the open anyway, breaking into abandoned houses and shops, climbing up, and traveling via rooftop was appealing.
It wasn’t working out exactly to plan, though.
As usual, the door to the roof opened with one hard shove from Oxman. But then, getting to the roofs was never a problem, and neither was jumping from building to building. The trick was getting across the streets. Old American roads were ridiculously wide, and had none of the overhangs you got in modern towns. Both men possessed certain items that quietly and discreetly boosted their ability to leap in straight lines, but every few blocks the two simply had to descend, sneak across one of the side roads, and make their way back up.
They stayed up top as much as they could anyway. It was that or stay on the ominously quiet streets — or worse, see what horrors the sewers held. In the Marcher lands, you only did that when you absolutely had to. You never knew what would be down there, except that it would always be filthy.
