Built during the Dark Age of Technology, it is believed the Telstarax was used to convey Medusa's minerals into space though its original purpose is still unknown. Even by the time of Ferrus Manus the Telstarax was an abandoned ruin, with a great portion of it having plunged onto the planet below. The structure has been studied heavily by the Techmarines of the Iron Hands. The Techmarines claim that they feel something within the Machine Spirits of the relic. A sense of anticipation. Of purpose as yet undiscovered, and of prospects that seem to lie just out of reach. What these may be is still a mystery.
