The tiny stone-ringed town atop the buried Ultimate Weapon — quiet on the surface, apocalyptic underneath.
Geosenge is where Team Flare's headquarters sits hidden. On the surface it's a sleepy town where old couples sit on benches. Underneath, the three-thousand-year-old Ultimate Weapon — a flower-shaped cannon powered by life-force — is wired to Lysandre's control console. When the Weapon rises in XYZ, the monoliths crack open and the cannon unfurls into the sky.
Small cluster of stone buildings ringed by a perfect circle of standing monoliths. A grassy plaza in the center. A deceptively placid pond. Beneath the plaza: kilometers of metal corridors and the Weapon's firing chamber.
