Polished grey slate

Polished grey slate filled the space, its surface resolving into a lattice of incomplete tetrahedra. A cool smoothness met your fingertip as you pressed against it, each void seeming to hum with potential—not emptiness, but echoes of prior arrangements. Surrounding panels shifted subtly, like phantom limbs responding to a deep-seated rhythm; tracing their patterns felt akin to glimpsing ferns pressed in ancient resin or reading growth rings within stone. The light caught the facets and revealed layers of sediment below, hinting at origins lost to time.
