Thaumaturgical Sector

The Thaumaturgical Sector, localised from 魔導区画 (Mystic Core), is the name given to the large section contained within the Orchis Tower as part of the Azure-Zero Project.

Background
The Thaumaturgical Sector's construction was masked within the overall construction of the Orchis Tower by the efforts of the Crois Family as part of their 1000 year Azure-Zero project. It contains their most advanced technology and draws upon their knowledge of the art of Alchemy. The public was led to believe that the floors containing this sector were empty and unused, and the elevator had restricted access.

The Sector is designed to draw orbal energy from each of the main four Geofront sectors, which were similarly disguised as ventilation, water processing, incineration and car parking facilities for the city. It then channelled this power, combined with the higher elemental energies from the Sun Fort, Moon Temple and Stargazer's Tower via the Tower's top relay into KeA and the three Aion units. Only the alchemists of the Crois Family are able to operate it.

Dieter Crois also claims the tower has a 'Soul Conversion Function' which allows him to convert himself into a form that can takeover and pilot the Aion Type-α from a form of Phase Space.

The first hints that such a facility exists were found when Jona Sacred was trawling through the data on the orbal network and discovered there was some sort of physical component to the data found there and a system designed to make use of it.

It is not until Dieter Crois makes a declaration of an independent Crossbell and the Special Support Section scale the Orchis Tower that they discover the Thaumaturgical sector, fully active and channelling power. Tio Plato finds the Eidolon Gear here, a prototype armament developed by the Epstein Foundation before it was stolen by Mariabell Crois and brought to the Sector. The area is also filled with Golems and Archaisms enhanced by alchemy.

Following the events of the Azure Tree, the Thaumaturgical Sector is deactivated and Rufus Albarea, as the Governor General, orders it to be sealed off.

After the fallout of the Great Twilight and the events at the Gral of Erebos, a party consisting of Estelle and Joshua Bright, Renne, Lloyd Bannings, Elie MacDowell and KeA infiltrate the tower to find out what had happened in the Empire. They had traced some data that had been sent to the terminal (unknowingly by Black Alberich's request). The Sector was largely deactivated and navigating it was not difficult, although they still had to contend with some golems on the way, and fight off Mariabell Crois, Alberich and Claire Rieveldt at the terminal. After Renne and KeA successfully crack the five-dimensional spirit code they find out what happened, too late to stop it and the party flees to to the elevator.

In their efforts to hold the third Rivalry, Rean Schwarzer's party infiltrate the Thaumaturgical sector once again to reach the rooftop and disable the barrier generator. The Sector is now fully active, with barriers and lift terminals that need to be disabled or bypassed and large numbers of golems are present. Also defending the Sector are McBurn and a curse-driven Victor S. Arseid. Alberich also deployed a Leviathan unit as additional insurance.

Machias Regnitz notes that the tower is once again gathering mana from nearby areas and channeling it to power the Aions deployed by the Society. Randy Orlando additionally notes that the area is different from when he was here last during the independence.
