The Lost Dimension (comic story)

The Lost Dimension was a miniseries published by Titan Comics. It served as a four-way crossover between Titan's ongoing series Doctor Who: The Twelfth Doctor, Doctor Who: The Ninth Doctor, Doctor Who: The Eleventh Doctor and Doctor Who: The Tenth Doctor, uniting the four Doctors and their companions, similarly to Supremacy of the Cybermen and Four Doctors.

Part one: Alpha
In a section of space, a white hole has opened and is consuming the surrounding space and planets. It has reached the planet, Sultath, where Jack Harkness and Tara Mishra are. Jack is trying to get the two of them off the planet, but interference from the hole prevents the vortex manipulator from working. He tries to contact the Ninth Doctor, but the interference affects the communication, and the Doctor assumes Jack is in a bar somewhere. With the Doctor not coming to their rescue, it seems all is lost, until the arrival of a mysterious woman in Gallifreyan armor.

At St. Luke's University, the phone in the Doctor's chambers starts ringing. Nardole answers the phone, and tells the person calling to hold, while he takes the phone and runs off down the hallway.

Over in the library, the Twelfth Doctor is looking at history books and tossing aside ones that are inaccurate, an act that makes it difficult for Bill Potts to study. Nardole arrives, handing the phone to the Doctor. The person on the other end tells him that she's dropping in for tea. The Doctor walks over to the nearby window and sees something that makes him turn around and yell for everyone to get out.

A bowship crashes into the library. The trio are perfectly unharmed, with Nardole protecting Bill. The Doctor remarks on the ship, before the cockpit opens, revealing the armored woman from earlier. However, the helmet is now off, revealing that she is Jenny, the Doctor's daughter.

Meanwhile, the Tenth Doctor, Gabby Gonzalez, and Cindy Wu are traveling in the Doctor's TARDIS. The Doctor is telling the two women about an adventure he had, when the Cloister Bell starts ringing. Suddenly, the trio find themselves in an earlier version of the TARDIS, and the Third Doctor is on the floor, being consumed by some white energy. The Tenth Doctor tries to help him, but the Third Doctor and his TARDIS fade away, leaving the trio back in their own TARDIS. According to the Tenth Doctor, the two TARDISes were merging, so his TARDIS had used an emergency temporal displacement to escape.

Back at the university, the four have moved to the Doctor's chambers and are enjoying some tea. Nardole is concerned. The Doctor assumes it's about the Vault, but he checked it, and it's completely fine. Nardole corrects him by saying he's more concerned about the crashed bowship, but the Doctor has dealt with that by calling in UNIT.

At the crash site, Kate Stewart has had the area closed off. Petronella Osgood marvels at the ship. But, as she touches it, her hand gets shocked by the strange white energy.

Back with the quartet, Jenny explains why she came here. After meeting Jack and Tara, Jenny tried to save them, but the white hole consumed the duo. Jenny rushed back to her ship and followed them in, hoping to save them. But, the ship couldn't handle the stress and it looked like Jenny was doomed. However, luck was on her side, as the Fifth Doctor came to rescue her. After failing to extend the TARDIS's gravity shield around the bowship, the Doctor was left with no choice but to ram Jenny's ship. The bowship was freed, but the TARDIS was caught in the gravity of the white hole and was consumed.

Meanwhile, the Eleventh Doctor finishes repairing the TARDIS's translation matrix, allowing Alice Obiefune to be able to understand what he's saying. An alarm starts going off, prompting the Doctor to go check the console. The Doctor reveals that he lied when he told Alice that hearing the Cloister Bell was the worst thing that could ever happen. The alarm is being caused by the TARDIS's Doomsday Circuit, which goes off when it detects the end of time, or, in this case, space. The TARDIS flies into the white void.

Back at the university, the Twelfth Doctor asks how Jenny found him. She tells him that this is the only place and time he has stayed still long enough for her to locate him, that she was able to access. Bill has heard enough and knows they need to do something to help the Fifth Doctor, Jack, and Tara. Running over to the TARDIS, she reaches out her hand to open the door. As she touches the door, she is attacked by the white energy, which enters her body. At that moment, Kate and Osgood arrive. The Doctor asks Osgood to help him analyze the white energy attacking Bill, but she refuses. Osgood, Kate, and the UNIT soldiers have been possessed by the white energy. Osgood states that Bill will soon know peace, and so will the others.

Part two: Ninth Doctor Special
On the Pacific Ocean, in 1886, a boat hits something in the water. Using a net, the men pull the object aboard, revealing it to be the TARDIS. The door opens and Rose Tyler steps out, wanting to know where she is. Not long after, the Ninth Doctor emerges. He gets into an argument with one of the sailors, only for it to be broken up by the captain of the ship, Madame Vastra, who welcomes the duo aboard the Mary Anning.

Inside her quarters, Vastra and Jenny Flint serve tea to their guests. Vasta and Flint explain to Rose about Vastra's origins. The Doctor asks Vastra why she's here. Vastra explains about how a Silurian corpse, one from the scholar class, was found and she is now looking for other possible Silurian survivors. The Doctor quickly dismisses the idea and starts to depart with Rose. But, Rose mentions that the Doctor's taking her to meet a guru who has three eyes. Vastra knows the Doctor is hiding something and confronts him, but before she can get any answers, the ship is hit by a creature who wrecks the boat.

The next morning, Rose awakens to find herself, the Doctor, Vastra, Flint, and a couple of sailors alive on an island. Vastra identifies the creature as a Myrka. She's angry at the Doctor for keeping his secrets, as they have now cost her the ship and half her crew. At that moment, the group is surrounded by Silurians. Vastra starts to greet them, but one of them shoots her. The Silurians take everyone except Flint away, while she stays behind to tend to the unconscious Vastra.

The group is led to the leaders of the tribe. The Doctor greets one of them, Horlak, who recognises the Doctor. Horlak asks the Doctor why he has come here. The Doctor brings Rose forward. After the incident with Addison Delamar, Rose's mind was left fractured. According to the TARDIS, Rose is on the verge of a full psychotic episode. Horlak reaches into Rose's mind and begins healing it. A voice calls out from within Rose's mind, one Rose recognises to be Jack Harkness.

Jack has established a psychic projection through Horlak, so he can communicate with the Doctor and Rose. The Doctor asks Jack how he pulled this off, and Jack steps aside to allow someone else to speak. To the Doctor's surprise, the person responsible is the Fourth Doctor. The Fourth Doctor explains that the universe is being devoured. But, the projection begins to break down. The Ninth Doctor uses his sonic screwdriver to boost the signal, but gets interrupted by the arrival of Vastra and Flint, resulting in the projection fading away.

The Doctor is furious with Vastra, but Vastra is just as angry. She demands for the Doctor to tell her why he hid this tribe from her. As it turns out, this tribe of Silurians have a disease, Raldoma Syndrome. It doesn't affect the scholar Silurians, but it does affect the warrior Silurians, like Vastra. Years ago, the Sixth Doctor helped set up this place, a location to keep these Silurians under quarantine, so they can't infect any other Silurians.

Rose calls out to the Doctor, pointing out that some of the Silurians have been infected by the white energy. Even Vastra and Flint get infected. Rose quickly picks up one of the Silurian guns and shoots Vastra, freeing her from the energy. The Doctor takes the gun and adjusts it with his screwdriver, allowing him to use it to free everyone else in the room from the corruption.

After freeing everyone, the Doctor asks Horlak if he can borrow another gun, as his modification ruined the first gun. Horlak agrees and states that he and the others will creating a telepathic dam to block the corruption of the white energy. As everyone begins to leave, Horlak calls the Doctor back, in order to give him another message from his past.

Later, the Doctor joins everyone else back at the TARDIS. The Doctor moves the TARDIS to 13 Paternoster Row. He then asks Vastra to look after Rose, as he's going somewhere dangerous that might be the end of him. The Doctor departs in the TARDIS. Flint assures Rose that the Doctor knows what he is doing, most of the time. Unknown to the two of them, Vastra and the sailors have been possessed by the white energy.

Part three: The Tenth Doctor
In his TARDIS, the Tenth Doctor stares at a projection of the Third Doctor being attacked by the white energy, while Cindy is wondering just how old the Doctor really is. Suddenly, the TARDIS shakes. The Doctor checks the console and sees they've encountered a temporal funnel and extreme gravitational stresses that are pulling the TARDIS off course.

The TARDIS ends up near a space station poised on the brink of the gravity well of a cluster of neutron stars. It's also linked to another region of space via a hyperspace corridor. The Doctor makes an emergency landing aboard the station, while wondering what kind of force could draw the TARDIS off course.

The trio step outside, and the Doctor realises that the station is a power refining facility, mining energy from the neutron helix. An alarm tells them that the station, Poseidon, is on lockdown. At that moment, two officers, Co-ordinator Akiyama and Senior Hyperspace Tech Mouchgober enter the room. They call out to the Doctor, apparently recognising him. However, it turns out they are mistaking him for Doctor Bell, who is supposed to be visiting the station to conduct an inspection. The Doctor and Gabby quickly trick them into believing that Bell is detained and that the trio are a replacement team.

The two officers bring the trio to Central Control, where Director Jessop is not happy to see them. The trio have come at a bad time, as the neutron helix, known as Hades' Helix, is flaring up. The helix is producing a large amount of electromagnetic radiation. The Doctor quickly moves over to a nearby console. With some adjustments, the Doctor not only fixes the shields, but improves them. With the immediate crisis resolved, Jessop asks Akiyama to take Cindy on an inspection tour, while he will show the Doctor and Gabby around Central Control.

Jessop explains that the station is the core collection point for the energy mining. They use collection probes to mine the energy. The probes beam the energy to the station, which transmits the energy through the corridor to the power collection plant at Ultima Tarsus. The corridor also serves as the anchor for the station, protecting it from the helix's gravitational forces.

Meanwhile, Akiyama and Cindy are down at the docking ports. Akiyama points out one of the collection probes, floating in space. She mentions that two probes when missing some time ago. Cindy notices that the probe is moving to dock with the station, something that the probes are not supposed to do. Cindy suggests it might be one of the missing probes. To Akiyama's shock, it is one of the lost probes.

Back in Central Control, Jessop tells the Doctor about the missing probes. One of the officers calls the group over to his console. According to the readings, the helix is collapsing inward at an impossible rate, becoming a black hole. The Doctor states it's not impossible, but is widely accelerated, possibly artificially. At that moment, Gabby gets a text from Cindy, about the missing probes docking with the station. The Doctor patches Cindy into the comm unit and tells her to get away from the docking port. Whoever is inside the probe is not friendly.

The station shakes as it's bombarded by time distortions. According to the Doctor, this is not a natural phenomenon, but one that's been engineered. Looking at a nearby screen, the Doctor and Gabby see the distortions are being caused by the white energy they saw attack the Third Doctor. The scanners then detect approaching ships, that turn out to be Cyberships. The Doctor yells at Cindy to run away from the docking port, as the station is being invaded by the Cybermen. At that moment, the docking hatch opens, and Cybermen start swarming into the station, attacking the security officers, while Akiyama and Cindy run.

Back at Central Control, the Doctor watches the Cybermen infect the security officers, with what looks like some new Cyber-virus. Mouchgober reports that the second probe is docking, which means there will be more of them, but Jessop has changed the access cipher, which will slow them down. But, as the Doctor points out, not for long, for the Cyberships arrive, and Cybermen starting flying through space, towards the station. The Doctor tells Jessop that he needs to evacuate the station, as this could be the only chance to get everyone to safety, especially with the helix collapsing into a black hole.

While Jessop gives the evacuation order, the Doctor talks to Gabby. The Cybermen were already here, planning the attack. But, the helix's sudden mutation means something else is going on here. Right now, they need to plot a safe route for Cindy and Akiyama to get back to Central Control. While Gabby does this, the Doctor overhears Jessop talking to another officer. The civilian personnel have been safely launched from the station and into the corridor. However, the Cybermen have trashed the lower docking ring. There are no escape ships left for the officers to use.

The station shakes, as the Cyberships ram into it. This baffles the Doctor, as the Cybermen aren't acting logically. Then it hits him. There is no Cyber-virus. It's the white energy, which has infected the Cybermen. The Doctor does a deep scan of the collapsing helix, and finds that it's not becoming a black hole, but a white hole. Streams of time distortions are emanating from the hole, reaching out for the station, even accounting for the station's continual drift. There is an intelligence within the hole.

The Doctor tells Jessop that he and his crew need to evacuate now. Since there are no escape ships, the crew will have to use the collection probes. The Doctor will use the station's power beam to push the probes through the corridor, allowing them to safely arrive at Ultima Tarsus. They should also destroy the station, so that the Cybermen can't use the corridor. The Cybermen were planning on taking over the station to use as a platform to stage an invasion of Ultima Tarsus. However, their plan was ruined by the white energy. Jessop and his crew need to make it back to Ultima Tarsus, to inform people about what happened here, so something like this can't happen again. Jessop agrees and begins working on the evacuation, and priming the station to self destruct.

Gabby then reports a problem. The increasing number of Cybermen is limiting the options she can use to safely guide Cindy. The Doctor points out that they can go through the vacuum core. But, the core is where the energy beam is generated and there's no air in there. Cindy hears this and tells the Doctor that she hates him. The Doctor ignores this and tells Cindy to go through the core.

Outside the core, Akiyama gives Cindy a cube, containing a self-enclosing E-Suit. All she has to do is tap the cube to her chest and the suit will form around her. As Akiyama begins explaining what will happen when they open the access hatch, Cindy puts on her suit. She then notices the Cybermen behind Akiyama and tries to warn her. But, it's too late, as a Cyberman grabs Akiyama, infecting her. Her suit cube files out of her hand and into Cindy's. The Doctor tells Cindy to not let the Cybermen touch her. She tosses the cube at the Cybermen, causing the lead one to stumble and slow down the others. However, the infected Akiyama grabs Cindy's ankle, just before Cindy opens the access hatch, and everyone is blown into the core.

The Doctor orders Gabby to go get Cindy and to take her back to the TARDIS, without removing Cindy's suit. The Doctor heads over to Jessop and his crew, who have boarded a collection pod. Jessop thanks the Doctor for his help, before launching the pod. The Doctor then re-aligns the energy beam, pushing the pod safely through the corridor.

The Doctor runs back to the TARDIS, noticing that the white hole has begun consuming the local space. At the TARDIS, he meets Gabby and Cindy. To his surprise, Cindy isn't infected. With no time to ponder on this, the trio quickly get inside the TARDIS and dematerialise, seconds before the station self destructs. The TARDIS is unable to get away, however, as one of the white hole's tendrils grabs onto the ship. As the Doctor ponders over everything, someone or something starts knocking on the door, which the Doctor proclaims to be impossible.
