Osiran War Pyramid Power Source

The white shiny pyramid stands at the base of the Osiran war missile, its polished surface reflecting the courtyard light with an unnatural luminosity. The pyramid emits a steady, pulsating glow that powers the missile's ability to transpose with its projection, bridging dimensions. Its presence is the fulcrum of Sutekh’s plan, a conduit for reality-altering energy that taints the air with an uneasy hum. Both the Doctor and Sarah Jane recognize the pyramid’s lethal purpose immediately, their focus sharpening as Marcus Scarman approaches and the Doctor voices urgent concern.
