Pulsing Overload Lights

The chapel’s dim light intensifies as Stael’s ritual nears completion, bleeding into sickly hues of green and crimson. Flashing beams lick the stone walls, their electric pulses synchronized with the alien entity’s awakening. Fendelman’s blood trickles in rhythm with the strobing glow, while the Doctor hesitates at the threshold, the charged air prickling against his senses. The lights betray the Fendahl’s imminent escape, their unnatural source betraying centuries of hidden power now breaking free.

Significance

Their abrupt extinguishing leaves the chamber devoid of familiar reference points, reinforcing the horrific unknown Sarah has become.
