Sisters of Karn reveal TARDIS location

Maren and the Sisters of Karn conduct a forbidden scrying ritual, using Maren's ring to pierce temporal secrecy and locate the TARDIS on their planet. The TARDIS materializes before them, confirming their long-held suspicions of its presence. The sisters' reverent incantations of Sacred Flame transform into urgent declarations of seeing an enemy machine, revealing the ritual’s true purpose: to seize control of the Doctor’s vessel. Maren realizes the TARDIS is a time machine and deduces the Doctor must be a Time Lord sent to steal their Elixir, marking a critical shift from ritual to concrete action against a foe they cannot mentally subdue.
