Object
Clockwork Egg Timer
A brass-geared timer no larger than a clenched fist, its white enamel face lined with Roman numerals and polished brass hands. The Doctor withdraws it from his coat pocket at a critical moment, turning the dial with a sharp click that sounds unnaturally loud in the forest's silence. Its ticking grows louder as unseen entities draw nearer, implying its vibrations can disrupt Xoanon's invisible mechanisms.
