History
On the 1st of January, 2019, a stranded Dalek whom the Thirteenth Doctor had been tracking using her TARDIS revealed itself to be a reconnaissance scout by making use of its special abilities to shrug off the TARDIS's detection systems. The ensuing short-circuit jammed the geo-feudal locks, forcing the Doctor send her companion Graham O'Brien for some peanut butter with which to grease the locks so as to restore their function.
