· Pyramids of Mars Part 4

Doctor and Sarah enter the Osirian tomb

The Doctor pries open the ancient sealed door of the Pyramid of Mars, revealing a dark chamber that hums with barely contained power. Sarah immediately recognizes the faint energy signature as a tribophysics field, a containment measure used by the Osirians to bind Sutekh within. The realization that this sealed tomb is more than a burial site hangs in the air. Every step deeper risks stirring the dormant trap, yet both know standing outside is no option—Sutekh’s will is reaching further than ever before. The chamber’s silence is deceptive; it is the quiet before the storm of the Destroyer’s awakening. key_dialogue: [ SARAH: Tribophysics. DOCTOR: Yes. ]
