Padmasambhava's Metal Pyramid (Inner Sanctum Control Device)

A metal pyramid in the Inner Sanctum serving as the Great Intelligence's core control device. Activated by Padmasambhava under the Intelligence's control, it summons Yeti into the monastery alongside a paired sphere. The Doctor witnesses its deployment during his mental duel with the Intelligence, while Jamie and Thomni target control panels elsewhere. Victoria remains paralyzed nearby. Later, the Doctor directs its destruction from the control room, timing the strike with the cave pyramid's remote detonation to shatter the Intelligence's grip and free Padmasambhava from possession. The pyramid's destruction resolves the monastery's invasion by severing the Intelligence's influence over Padmasambhava and the Yeti.
