Lagh

From Tardis Wiki, the free Doctor Who reference

Lagh was a mineral utilised by certain advanced civilisations. Known as a "mental silicate", lagh had properties that made it a useful component in technologies interacting with thought or consciousness. It was generally solid, shiny, cold to the touch, and black in colour, and was sometimes mixed with metals to create lagh alloys.

The posthuman citizens of the Solar Kingdom of Orniticon used telepavision, a video format experienced telepathically, and which depended on lagh wiring to function; as such, Orniticon's servitor robots with built-in telepavision screens included lagh components.

The Superiors used lagh; at one point, they mined it from a colony in the Amazolian system, though this colony had been abandoned and forgotten by Chris Cwej's time. A female friend, who had recently become a mother, also told the Third Cwej about crystals with lagh-like properties.

Lagh technology played an instrumental role in the conclusion of the War in Heaven. In the V-Time Experiment, a slab of Amazolian lagh was stored outside time for several decades, sterilising it of past history; Chris Cwej's consciousness was then transferred to the slab, after which it was divided and implanted in the bodies of millions of Cwejen, enabling him to possess any of them at will from across spacetime. This system was anchored and coordinated by the Vicinity, an intelligent virtual reality housed in a small cube of lagh and glass. (PROSE: The V Cwejes)

The expensive carved chandelier of the dinner hall of one corrupt human C.E.O. who lived centuries after the Cyberon War was made of an alloy of lagh and electrum. (PROSE: The Blue Scream of Death)
