Boulder physics rule the depths: one careless dig starts an avalanche — one clever dig starts a fortune. Meet the coin quota, find the exit, and get out before the timer or the dark gets you. Cozy on the surface. Deadly underground.






Every travel ticket carries Cora one layer deeper into the past — from sea caves, to sealed Victorian mineworks, to halls no history book names.
Sun-shafts, tidal grottoes and drowned galleries beneath a southern harbor town. The sea made these caves — but something built the lowest halls.
The Thornwall Mining Company dug too deep in 1870 — then sealed the lower levels and vanished from its own records. The rails still creak.
Carved pillars, engraved walls, mechanisms from no known civilization — and a castle built for one purpose: to cap what lies below.

Chests hide named antiques — a drowned chapel’s bell, a foreman’s watch stopped at 4:11, an idol from no known culture. The moment Cora lifts one, it’s written into her catalogue forever: sell the object, keep the knowledge. Fund the journey without losing the mystery.
“Stopped at 4:11. Nobody has ever offered to say why.”— Foreman’s Watch, Old Mines, Level 3
Three months ago her mentor packed a bag and vanished, leaving a journal, a hand-drawn map, and three place-names. An oil lantern, a satchel, and whatever the ground gives up — that’s the budget. The trail runs north, and it only gets darker.
It’s 1928. Zeppelins stitch the sky, radio crackles in the parlors — and past the mine gate, the modern world stops at the threshold.
