TARDIS control room (The Ghost Monument)
Due to the Twelfth Doctor holding his regeneration back for too long, the console suffered major damage, causing the TARDIS to malfunction and drop the Thirteenth Doctor out as it vanished (TV: Twice Upon a Time) to Desolation in a materialisation loop. The TARDIS remained on Desolation for centuries trapped in the loop, and it was known as "the Ghost Monument" by Desolation's former inhabitants. When the Doctor and her friends arrived at Desolation, they found that the TARDIS had taken on a new interior appearance. (TV: The Ghost Monument)
Appearance
The entrance to the TARDIS had the side walls of the inside of the police box, while the back of it led into the main control room. The walls of the TARDIS were made of non-connected walls made of hexagons containing a cog-like pattern. There were also a few blue lights in the walls, along with a hexagonal monitor, as well as a metal cage-like framework around the console platform with hexagonal shapes. (TV: The Ghost Monument) In place of a proper monitor at the console was a blue holographic image on the side. It only displayed Gallifreyan language. (TV: Rosa)
The console itself lacked a conventional time rotor, which was replaced with a giant crystal that glowed orange while in use. Six other crystals were formed around the console. Instead of keyboards, there were more steampunk-ish controls such as levels and nobs. There was even a tiny replica of the TARDIS on the console, which spun when the TARDIS was in flight. To the Thirteenth Doctor's surprise, the console also included a foot pedal; upon pressing it, a dispenser on the console would produce biscuits. (TV: The Ghost Monument, COMIC: The Forest Bride) This console also had a telepathic circuit of its own kind, as used by Yaz when travelling back in time to visit her grandmother's wedding. (TV: Demons of the Punjab, The Battle of Ranskoor Av Kolos)
The giant crystal taking the place of the time rotor could be seen rising and falling while the TARDIS was in flight. (TV: Rosa) The top parts of the surrounding crystals would also move along with the central crystal, like an arm. (TV: Demons of the Punjab)
The blue lights in the framework around the console platform replaced generic roundels as access to circuitry (TV: The Battle of Ranskoor Av Kolos) and general storage. (TV: Revolution of the Daleks, The Power of the Doctor) The Doctor referred to them as 'portals'. (TV: The Battle of Ranskoor Av Kolos)
At some point after the Doctor's encounter with a Dalek reconnaissance scout, (TV: Resolution) the TARDIS had added a few new features to the control room. Near the back of the room was a set of stairs made of hexagonal steps leading to a small platform, as well as a doorway leading deeper into the interior; the six crystals surrounding the console were now stationary at all times, and had more sturdy-looking supports at their bases; above the console, directly over the giant crystal, sat a second, similar crystal pointing down from a spherical protrusion made of the same hexagonal framework around the control room; and on the console, new holographic moniters had been installed, allowing a display of images for the Doctor and her companions to see. (TV: Spyfall) Towards the entrance there was also a bioreading synthesizer that could ascend from and descend back into the floor activated from the console, which was used to scan and prepare antidotes, (TV: Praxeus) whose top panel could function as a table. (TV: Orphan 55)
When time began running wild due to the Flux damaging the Temple of Atropos, the TARDIS began malfunctioning, resulting in deformities in the control room such as spikes growing from the walls, (TV: War of the Sontarans) black liquid oozing from the crystals surrounding the console and multiple police box doors. (TV: The Halloween Apocalypse) Once the Flux was resolved, the Doctor reset the TARDIS to resolve these problems, with the control room collapsing into a void whilst the ship reset. Afterwards the control room was restored to normal. (TV: Eve of the Daleks)
Inherited
This console room was briefly inherited by the Fourteenth Doctor. (COMIC: Liberation of the Daleks) However, mere hours following the Thirteenth Doctor's regeneration, (PROSE: The Giggle [+]Loading...["The Giggle (novel)"]) it was replaced by a new control room, which the Doctor discovered after thwarting the Meep's attempted destruction of London. (TV: The Star Beast [+]Loading...["The Star Beast (TV story)"])
