Kastrian Dome Tripwire Trap

A taut, thin cable strung across the walkway at the edge of the Kastrian dome’s abyss, hidden just beneath loose floor panels. Sarah yanks the wire on the Doctor’s command, triggering the trap’s mechanism that sends Eldrad stumbling toward the chasm. The physical rigging is barely visible until activated, its simplicity belying its effectiveness in a moment of high stakes.

Doctor outsmarts Eldrad with decoy ring

The taut tripwire cable, hidden beneath the loose floor panels near the abyss, is activated by Sarah at the Doctor’s command. It sends Eldrad stumbling off balance directly toward the edge and into the abyss, fulfilling the trap’s purpose with mechanical precision.

Before: Concealed but primed across the walkway over the abyss, ready to be triggered

After: Likely returned to a relaxed state after Eldrad’s fall, still in place but no longer serving an active function
