The Clockworks

The Clockworks was a place of logic and reason maintained by Iris Wildthyme's people, (AUDIO: Iris Wildthymen and the Land of Wonder) who kept the multiverse structured and orderly. (PROSE: Wildthyme Beyond!, AUDIO: Iris Wildthymen and the Land of Wonder) Everything was watched and recorded from the Clockworks. (PROSE: Future Legend)

The capitol of the Clockworks was Saga City. (PROSE: Wildthyme Beyond!) It was ruled by a council, who were responsible for the banishment of the Monstrons millennia before the 42nd century. (AUDIO: The Iris Wildthyme Appreciation Society) Spectacular forests grew at the heart of the cities in the Clockworks. (PROSE: Wildthyme Beyond!)

In some accounts, the name of Clockworks referred not so much to the location as to the civilisation that sprang from it; the Clockworks were there described as one of the oldest species in the multiverse, who, when it was still young, (PROSE: Elementary, My Dear Sheila) had been tasked with maintaining the basic structure of said multiverse. (PROSE: The Blue Angel)

According to other accounts, the Lords Temporal were "the most powerful race in the Clockworks". (PROSE: First Meetings) The Carnival Queen referred to the Spiral Politic as the "Majestic Clockwork". (PROSE: Christmas on a Rational Planet)

History
Iris thought the people of the Clockworks were the oldest civilisation in the multiverse and rotten to the core. (PROSE: Iris Wildthyme and the Colonic in Space)

When the multiverse was still young, the people of the Clockworks were allied with the Sentients, the Modulars, the Recursives, the Binaries, and many more species. (PROSE: Elementary, My Dear Sheila)

Iris told Panda that she had lived as in the slums miles outside the Clockworks. (AUDIO: Itis Wildthyme and the Land of Wonder) According to other accounts, as a girl, she lived in the mountains of the Clockworks with her Aunts. (PROSE: Wildthyme Beyond!, First Meetings, Iris at the V&A)

After Iris Wildthyme left the Obverse into the universe, the Clockworks followed her and remained on Hyspero for millennia while they waited for her to return to them. (PROSE: Wildthyme Beyond!)

The fabled Key to the Clockworks, if assembled into a cube from its six segments, would allow the user to open the gateway between universes at will. (PROSE: Future Legend, Iris Wildthyme and the Unhappy Medium)

Behind the scenes

 * It has never been clarified if the Clockworks is a species, a country, a planet, or even a galaxy. The term could be a description of a domain through time and space, similar to the Faction Paradox series' concept of the Spiral Politic.
 * The residents of the Clockworks are occasionally referred to as "the Clockworks" by metonymy, or, more rarely, "Clockworkers", but they are never given a more definite species name. First Meetings establishes that the "Lords Temporal" are the most powerful race in the Clockworks. In other Iris Wildthyme stories, including The Scarlet Empress, Verdigris, and The Elixir of Doom, Iris and her House of Aunts have been identified as coming from Gallifrey.
 * PROSE: From Wildthyme with Love features "Iris Wildthyme's mysterious superiors" without elaborating on whether they are, in this context, the Time Lords, the Clockworks, or some other faction entirely. In that story, these superiors are mentioned to have a Supreme Being as a leader and to have been seemingly destroyed by a version of Iris at the conclusion of an "epic rave" known as "the Tim War". Notably, Cwej: The Series would later use a capitalised "Superiors" to refer to a similarly ambiguous faction who could plausibly be interpreted as standing in for the Great Houses of the Time Lords, for the Higher Evolutionaries, or indeed for the Clockworks.
