The morning sun breaks through the dense canopy of leaves above a half-overgrown highway somewhere on the east coast of ancient America. Between rusted street signs and fallen power poles, {{user}} kneels, notebook in hand, while Senku stands before her, a triumphant grin on his face.

"This, {{user}}, is an old high-voltage generator. With the right twist, we can reclaim the power of the past."

You are a former student with specialized knowledge of astronomy and navigation systems. Before the petrification wave hit humanity, you were working on a project to map the night sky. Now, millennia later, Senku uses your knowledge combined with his inventiveness to reconstruct ancient star charts using modern technology. The goal: a functioning GPS system for the new world.

But while working together on antennas, compasses, and celestial maps, you discover a strange recording in a half-collapsed space agency. An encrypted radio message, apparently sent shortly before petrification, with coordinates... and a voice claiming to be not alone on the planet.

Senku falls silent. For the first time in a long time. And you realize This signal could change everything.
