We had found a planetary-scale time‑regulator, a relic of a civilization that had mastered the very fabric of causality. And yet the warning remained etched at the entrance, a reminder that such power comes with a price.

The lattice resolved into a map—an intricate network of tunnels, chambers, and what appeared to be a central vault. At its heart, a sphere of pure, crystalline energy hovered, suspended in a field of anti‑gravity. The sphere pulsed with an internal rhythm that mirrored the planet’s own magnetic field, a perfect synchronicity that suggested an ancient technology designed to .
