Energy pattern
From Tardis Wiki, the free Doctor Who reference
The energy pattern of the Doctor's TARDIS was identified by Dalek Command, who dispatched a group of bronze Dalek Executioners to Earth on 31 December 2021 to intercept and exterminate the Thirteenth Doctor, who they believed responsible for the destruction of the Dalek War Fleet in the final Flux event.
