Château de Tiffauges
A gigantic device that takes its name from a taboo castle, where acts of immorality occurred nightly.
It is also the residence of Carol and her dolls, a patchwork created by various relics and heretical technologies.
Currently it remains under construction, however all that remains are the trigger parts necessary to activate and control the machine.
Once that is complete, it can be used as the "World Destroyer".
A large device constructed to dissect the world. It is known as the "World Destroyer".
It was mainly utilized by the alchemist Carol during her involvement in the Magical Girl Incident,
however it is believed that Prelati also had a hand in its construction (mainly the design).
This is supported by some of what Prelati has said and done in the series thus far, but there is another main reason.
In the past, Prelati committed atrocious acts of evil for pleasure in a castle that shares the same name.

A mega-structure known as the "World Destroyer" that was constructed by Carol during the Magical Girl Incident for the purpose dissecting the world.
At the end of a fierce battle, it collapsed above the former metropolitan government building and fell under the management of the Kazanari Organization.
However, due to the complex interaction of a number of heretical technologies, the situation must be handled very carefully and demolition of the structure has been proceeding slowly.
Its breathtaking presence rises to the heavens like a gravestone.

The demolition of Château de Tiffauges began with the installation of a large power generator, lighting, elevators, and finally heavy machinery.
This was merely a front to construct a large-scale secret hideout in the heart of the city.
Under the disaster prevention law, management of the facility was entrusted to the Kazanari Organization.
With great efforts, they were not only able to establish a ritual altar to house the vessel of the divine power and a generator to extract energy from the rejected bodies, but also establish Noble Red as the occupants of the Château.
XV Episode 8
In order to operate the tremendously damaged and deactivated Château de Tiffauges, the adaptors attempted to restart it via phonic gain.
Completely incomparable to previous excitations involving the Staff of Solomon and Armor of Nehushtan,
they had anticipated the difficulty of activating the composition of numerous relics that was the Château de Tiffauges,
and projected that a synergistic explosion of climax song could achieve a forcible breakthrough of phonic gain ―
but in the end, their efforts ended in failure.
