Mine Chamber Shaft
Sorba identifies the shaft as the mine chamber's only access point, an inescapable vertical tunnel piercing solid rock walls. He frames it to crush escape hopes, but the Doctor spots a fragile water bowl nearby, proof of hidden infrastructure that contradicts the tomb claim. Zoe and Jamie shift from resignation to search as the shaft stands as their visible yet daunting barrier.
