Doctor shatters Wrack’s power-source gem

The Doctor seizes the moment of Wrack’s temporal ascension to act with desperate precision. Sprinting into the grid room, he snatches the glowing tiara from the floor and crushes its central gem with a fire axe. The Black Guardian’s voice, emanating through Wrack’s form, howls in a mounting frenzy as the ritual unravels before her very eyes. Wrack’s visage fractures into a spiraling vortex of writhing faces, the corrupted power spinning out of control as the gem’s destruction destabilizes the channel binding time itself. The Doctor knows the cost—this gamble could collapse both Wrack’s scheme and the fragile structures of time around them, but he chooses rupture over ruin.

Tegan's Edwardian Tiara (Temporal Conduit)

The tiara, its central gem pulsing with violet temporal energy, is violently wrenched from Tegan’s bed by the Doctor mid-stride. He places it on the cabin floor and severs the glowing gem with the axehead in a single, decisive strike—its energy exploding outward as the ritual conduit fails.

The Doctor wrenches the fire axe from the panelled wall in the grid room and carries it into Tegan’s cabin, where he uses it as a tool of disruption—moving with purpose across two spaces in seconds. He places the axe to the glowing tiara on the cabin floor and strikes its central gem with a single concussive blow, shattering the conduit.
