Lead-Lined Scanner Beam Array

The scanner beam will be activated by Colby to disorient the Fendahl, creating the window necessary for the Doctor and Leela to retrieve the skull before the lead-lined box triggers the implosion.

The scanner beam array, powered by the lead-lined box, is the Doctor’s only defense against the Fendahl’s psychic detection. Colby’s two-minute activation creates a window of confusion, allowing Leela and the Doctor to descend unnoticed while masking their approach.

Seconds before the Fendahl reaches critical mass, the scanner beam is abruptly shut off, terminating its electromagnetic interference that had partially contained the entity. Its cold blue glow vanishes, leaving the Doctor and Leela staring into the gulf of impending completion.
