The Castlerose Apparatus is a technology, developed by the Qui Err as a response to independence, and later refined by Miss's Castlerose and Our Profit and her scientists. Granting the ability to print bodies, and install or revive their consciousness, it grants the user a degree of immortality.
History
The technology was developed by the Qui Err and was present aboard Sky Reflected in Mirrors when it was found by the Divine Curiosity and brought to the fleet. Eventually, the technology was found by Miss's Castlerose, who employed it as part of an assassin organisation.
Post Miracle
Following the Miracle of the Mirage, Miss's Castlerose sold the technology to the New Earth Hegemony. It then made its way to Earth and lay unexplored for many years, until Our Profit's scientists rediscovered it while investigating ways to create a utopia. It then began being used again, granting Our Profit the ability to travel to the Quire System, a long trip that took more than a lifetime to complete.
