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 space around the TARDIS is being consumed by 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 Jenny 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, Jenny, 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 Jenny 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 recognizes 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 recognizes 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 Jenny, 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 Jenny 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. Jenny 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.
