Theater on the ninth level of Larracos concealing the shielded signal antenna the crawlers must destroy.
Donut, spotting from the The Nest tower, catches a reflection off a building across the way and realizes the antenna is inside the Piccadilly — the theater on the ninth level of the city. The enemy deliberately placed it where she couldn't see it from her perch.
She can't shoot it: the angle is wrong, she only sees it via reflection, and there's a shimmer of a shield around it. Worse, the advancing lava is about to land directly in front of it and block the sightline entirely. Carl plans to push to the railing at the Larracos College of Magic to gain line of sight and start lobbing Waffle Maker bombs onto the theater instead.
A theater building on the ninth tier of the funnel city, glimpsed only as a reflection through smoke, wrapped in a shimmering shield.
The hidden generator site and the target of the entire bombing run.
