Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.
Fearing he is lost in a parallel world, the Doctor and Gus take off in the TARDIS. Orbiting Earth, the Doctor sees a magnetic anomaly emanating from near the North Pole has created many parallel worlds. The Doctor and Gus land near the anomaly to find its source is a spaceship. Sneaking into it, they find the Time-Meddler and a party of Ice Warriors led by Autek, who are building a giant sonic cannon.
An advanced, secret and surprisingly well informed military group, SAG 3, is also investigating the anomaly. As the Ice Warriors prepare to drop the Doctor into a pit, SAG 3 attacks the ship, frees the Doctor and forces the Ice Warriors to leave Earth. In his TARDIS, the Doctor pursues the Time-Meddler's TARDIS through space and time. After a chase through the Time Vortex, the Doctor appears beforethe Time-Meddler, who attempts to materialise in the same spot. Having two TARDISes in the same place and time causes an explosion which destroys the Ice Warrior ship and sendsthe Time-Meddler to another dimension.
Having solved the mystery of the parallel worlds, the Doctor and Gus part ways with SAG 3 and go on to their next adventure. After the TARDIS dematerialises, SAG 3 are left to wonder if they should have told the Doctor that Gus was going to die...
The Time-Meddler theorises that the sonic cannon will be able to even destroy a TARDIS. The equipment functions by use of a special focussing crystal, which is implied to be true of all Ice Warrior sonic cannons, if not handheld weaponry. The gem intended for the superweapon is created in a crucible of compressed molten silica, seeded into the Earth's crust and retrieved millions of years later.
SAG 3 are a psionically-active paramilitary unit dispatched from a hidden base in Scotland. Their members are capable of telepathic conference, telekinesis and, in one extraordinary case, precognition.
The Time-Meddler and his TARDIS are so "perfectly annihilated" that they're transported to another dimension.
The Doctor considers Earth a second home, and is disturbed at the prospect of being lost in time on a parallel Earth different from the one he's known.
The Time Lords issued the Doctor with a grenade-sized device capable of cancelling out a time warp.
This is the first appearance of the Meddling Monk in a comic story. This rendition of the character is visually based on Peter Butterworth's TV version. While no specific mention is made of the circumstances surrounding their meetings -- in TV: The Time Meddler or TV: The Daleks' Master Plan -- the Monk's TARDIS remains in the shape of a police box. A product of the Doctor's interference in Egypt during his escape from the Daleks. Without ready explanation in 4-Dimensional Vistas itself, it exists as an unusual nod to televised continuity in this era of the Doctor Who DWM comics.
The character is depicted as going by the name of "the Time-Meddler," with the assumption that the nickname of "the Monk" was simply a nickname named on his specific disguise in medieval Northumberland. Later usage of the character, however, would elevate "The Monk" into the character's default alias, equivalent to "The Master" or "The Rani", although occasionally with the man himself complaining about others having begun to call him that without his consent.
The Doctor comments that every time he activates the TARDIS, he's sent sideways in time, implying that perhaps all the Fifth Doctor's comic stories have been set on parallel Earths.
For the purposes of this list, an "Ice Warrior story" is one in which one living, authentic Ice Warrior plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story.
