Fire and Brimstone (comic story)

Fire and Brimstone was a Doctor Who Magazine comic story featuring the Eighth Doctor.

Summary
The Doctor and Izzy materialise in a small satellite orbiting Crivello's sun, and witnessed an attack on it by Daleks. While attempting to stop the Daleks' plans, it is revealed that another of the Doctor's deadliest enemies, the megacorp known as the Threshold, was hired to destroy the Daleks, and already had a plan in motion. This plan fails, and Izzy escapes with the Threshold's payment and a portal-generating Threshold ring. She warps to the Doctor's location, who has been informed of the Threshold's mission, and knows who hired them: After all, the box containing their payment was embossed with the Seal of Rassilon. The Doctor manages to defeat both the Daleks and the Threshold by making Crivello's sun go nova. However, as the Doctor and Izzy escape in the TARDIS, a Threshold agent appears to remind the Doctor of his hollow victory and their continuing machinations.

Characters

The Doctor

 * The Doctor visited Discworld in spite of its status as a work of fiction by Terry Pratchett on Earth.
 * Once captured and pinned by the Daleks, he remarks that he hasn't felt as ill since he flew across Old Baghdad on a magic carpet in an as yet undisclosed adventure.
 * He maintains a link with the heart of Crivello's Cauldron and can sense his connection to it through his symbiotic nuclei.
 * The High Evolutionaries of the Matrix are implied to have been responsible for shifting his TARDIS from Icarus Rising to the Dalek Hive during the critical moment when the Doctor convinced the Ptolemy-Cauldron entity to go nova and plug the wormhole linking our universe to every alternative.

Daleks

 * The Daleks use the contagium to penetrate the inner sanctum of Icarus Falling, overpowering all aboard the station save the Doctor, Izzy and Chastity and turning them into submissive husks slaved to the will of the Dalek race.
 * The Dalek Hive is a space cruiser composed of three billion tonnes of solid dalekanium and is propelled by a series of engine units capable of generating a force equivalent to that of six hundred erupting volcanoes.
 * The Threshold have attempted to work with the Daleks in the past, but found the experience wanting and have refused to work with them again.
 * The Supreme Dalek is monumental in size and has a literal eye in its stalk, which can be used to infer rage.
 * They encountered an alternate version of themselves in a spatiotemporally displaced vessel found deep within the Magellan cluster during the fiftieth century. It was vivisected by the Daleks' scientific division and found to be similar in form to that of their own species, warranting their total extermination from the face of this universe and all its alternatives.

Continuity

 * Crivello's Cauldron last appeared in COMIC: The Keep.
 * The Doctor references the death of Ace in COMIC: Ground Zero.
 * While it appears the box comes from the Time Lords, COMIC: The Final Chapter and Wormwood reveal it to be from Rassilon himself.
 * The Doctor visited the New Earth System in his fourth incarnation (COMIC: Doctor Who and the Dogs of Doom).
 * The Dalek Contagium used to infect the Leaderene could theoretically be a technological extension of the Mutant Phase that plagued them in the story of the same name. Alternatively, the virus could have its origins based in or is a prototype of the weapon seen and used in PROSE: The Dalek Factor.
