After connection to the Eye of Harmony the Space-Time Event is moved to Neural Construction Docks. To protect Gallifrey from time pollution the docks are located outside of Gallifrey's star system. The Docks are equipped with Filter circuitry to generate Transduction Barriers. These barriers are used to prevent the Capsules from escaping. Inside the Docks are numerous Dimensionally Transcendental Cradles which hold the future TARDISes. The Time Lords alter this Metastructure to make the Event dependent on the Symbiotic Nuclei of a Time Lord for its ability to travel in the Vortex.
It is at this point that the Space-Time Event becomes a viable Time Travel Capsule.
TARDIS sentiences are created with a Block Transfer System using specific Artificial Intelligence Code. Using Birthing matrices the block-transfer A.I. is rendered and physically formatted into an organic Protyon Unit that serves as the brain of a TARDIS. The Protyon Unit is then implanted in the Space-Time Event and programmed with multidimensional Grey-Prints of the new TARDIS. Grey-Prints are designed by Gallifreyan Mathematicians and set down many of the specifications and capabilities of the new TARDIS including its gender. At this point the Capsule uses Warp Matrix
(Transdimensional) Engineering
to grow its interior and exterior shells. Using these Grey-Prints as guide, the Protyon Unit grows the interior/exterior of the Capsule,
starting with the Time Sceptre.
The Cloister Room (with the link to the Eye of Harmony) develops first, followed by the rest of the
Sceptre.
Several pieces of
exitonic
circuitry are implanted by the Time Lords, including
the Temporal Drive
and Chameleon Circuit.
Exitonic
circuits are made of a type of metal that has many of the characteristics of plastic.
If the Capsule is designated female, it will receive XX circuits, if male, XY circuits.
Once the Protyon Unit has generated the necessary interior and exterior shell
the Capsule is considered to be a fully operational Time And Relative Dimension In Space (TARDIS) ship.
The word "Tardis" means Time-Ship,
however the plural of TARDIS is still debated by Time Lords. When a TARDIS acquires extra internal dimensions its acronym changes from Time and Relative Dimension in Space to Time and Relative Dimensions in Space.
When running in a new TARDIS (or a TARDIS with a new Dynomorphic Generator), the operator should navigated an already established vortex wormhole (such as a Time Contour or a Time Corridor) to check out the temporal dimensions.
This is a good way of testing the engines on low power it requires less energy.
It should be noted that with the proper plans and expertise a Time Lord can construct a TARDIS using primitive technology (such as that found on Earth in the late 20th century). This can be done in a relatively short amount of time.
It is also not unknown for lesser species to attempt to illegally clone TARDIS.
