Tarzan placed his palm on the stone. The glyphs responded, aligning themselves in a pattern that resembled the HDHub icon. The door shuddered and began to open, revealing an underground chamber bathed in ethereal light. Inside the chamber lay a colossal sphere, suspended mid‑air, surrounded by concentric rings of crystal. The sphere emitted a harmonic hum, resonating with the same frequency as the HDHub4U device.
