At the end of the hallway, she found a hidden door—its wood paneling slightly warped, a small crack in the center where a faint blue light leaked out. She placed her hand on the crack, and the blue light surged, forming a holographic map of the city.
The map highlighted a series of underground tunnels beneath the library, each labeled with numbers. One tunnel, marked “67,” pulsed more brightly than the others. Maya descended a spiral staircase into the earth. The tunnel walls were lined with copper wires and old server racks, humming softly.
