Warpsmith

The Warpsmiths, also known as Warpwrights, Phaidons or Phaidonians were a time-active species from the planet Phaidon and members of the Temporal Powers. (AUDIO: Appropriation) The Warpsmiths were seen as a credible threat to the Braxiatel Collection. (PROSE: Parallel Lives)

Nature
The Warpsmiths were incorporeal and made agreements with physical beings to allow them to inhabit their bodies for a set number of years. Whilst the Warpsmiths called such individuals bondspeople, Andred, who found the process disgusting, called them slaves. (AUDIO: Weapon of Choice)

History
Warpwright Ambassador Kalbez orchestrated a plot to assassinate the President of Phaidon and blame a terrorist attack on Gallifrey on the Monan Host, in order to form an alliance between the Warpwrights and the Time Lords. However, this was averted after Romana II altered the timeline. (AUDIO: Enemy Lines)

Most of the nine-billion population of Phaidon was exterminated by the Daleks at the onset of the Last Great Time War, with only five thousand survivors taking refuge on Gallifrey. (AUDIO: Celestial Intervention) This, along with the extermination of the Nekkistani, Sunari and Monans, led to Gallifrey formally declaring war against the Daleks. (AUDIO: Desperate Measures)

Behind the scenes
The Warpsmiths first appeared in The Yesterday Gambit, a standalone Marvelman comic story printed in Issue 4 of  in 1982, written by Alan Moore and drawn by Steve Dillon.

In A Chronology of Everything (Almost), the internal document created by Alan Moore and Steve Moore to nail down the timeline of the shared universe of all publications within Warrior, it was revealed that the Quality Universe was to the Doctor Who universe (for whose Doctor Who Magazine comics both men had written) as "Earth-2" did for the primary Earth of DC Comics at the time. The primary point of divergence was that the Quality Universe's Chronarchy (a name coined by Moore for the Time Lords in his contemporary Doctor Who comics) were all but wiped out by the Warpsmiths around the year 1700, when they sent the Death-Cats to destroy them.

These events were never clarified in an in-universe narrative. However, as documented above, the less successful N-Space versions of the Warpsmiths ultimately appeared in official Doctor Who media, with Enemy Lines further displaying their hostility towards the Time Lords.
