Gorgon at Tier 3 / two-story jump with minimal effort

One of the Seventeens moaned and I glanced away, just for a second. She was gone when I looked back.
I was tier three or so, enough that a two-story jump was just possible with a little effort. I took a running start, hit the center line of the street, and leaped.
I landed on the bleached tar paper of the roof. The goggles were open, draining anyone who caught sight of me, but there was no one. I looked behind some air vents and an access door. She’d vanished like some little ninja-stealth adept.
