Discovery of underground slave labor

The Doctor and his companions descend into the planet's underworld and confront its deepest horror: generations of enslaved laborers perpetually toiling in the caves. Naia reveals the brutal system of population control through skyfalls and the suffocating cycle of processing rock into food to sustain their existence. The Doctor recognizes this subterranean civilization as descended from the lost P7E crew, connecting their suffering to the original crew's doomed mission. This revelation not only exposes the cruelty of the Seers' regime but also presents a critical tactical insight—the existence of an unguarded goods entrance into the citadel, offering a potential path to infiltrate their stronghold.
