What Awaits You

Step 1: The Excavation Edge

You step through the opening and into the earth. The air tastes of wet stone and something else — something older. Your boots sink into soft clay. The walls rise above you, raw and unrefined, like a wound that's been healing for two thousand years. You press your palm against the cold surface. It's warm beneath. Your fingers trace the rough texture of mortar, the way it's worn smooth in places by hands that came before. The ground trembles slightly — not from your footsteps, but from something deeper. You hear it now: a low, rhythmic hum, like a heartbeat buried under centuries. You pull back. The sound is stronger. Not just your own pulse — a pulse from the stone itself. The air grows thick with heat. You can smell it — not the sharpness of fire, but something deeper, mineral, like the breath of the earth. Your skin tingles. You are not alone here. The silence is full of waiting. You take a breath. The steam begins to rise.
