Thaumaturgical Sector

Hold on, it looks like Millium wants to tell you something.

Hey-hey! White Rabbit here! Lammy scanned this article and said it contains unmarked spoilers for all Trails games. Turn back now if you don't want to get lasered! Okay, byee!

The Thaumaturgical Sector (魔導区画) is the hidden core of Orchis Tower, consisting of the alchemical machines that make part of the Azure-Zero Project.

Trails to Azure[]

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 project. It contains a mix of the most advanced orbal technology and alchemical science. The public was led to believe that the floors from 21 to 30 were empty and only present for structural purposes, with the elevator having restricted access.

The Sector was designed to draw and purify orbal energy from each of the main four Geofront sectors, which were similarly disguised as ventilation (A Sector), water processing(B Sector), incineration (C Sector) and car parking (D Sector) facilities for the city. Combined with the higher elemental energies from the Sun Fort, Moon Temple and Stargazer's Tower, the tower channeled this energy through the relays on the roof into KeA, situated in the Castle of Mirrors at Mishelam, forming the fourth point of the alchemical cross and ascending her to the Sept-Terrion of Zero.

After the Special Support Section deactivates the barrier surrounding the city and assaults the tower with the resistance, they take the elevator to the Thaumaturgical Sector, still channeling energies strong enough to drain the EP from their ENIGMAs. The SSS traverses the sector to make their way to the 30th floor terminal, where Jona Sacred and Chief Roberts helped them unlock the security doors to the higher floors. They also find the Eidolon Gear here, a prototype exoskeleton developed by the Epstein Foundation as a successor to the first Orbal Gear, before it was stolen by Mariabell Crois. Tio Plato is able to link with it and use it in their following battles.

At the roof of the tower, the SSS confronts Dieter Crois, who uses the energies of the tower to move to a Phase Space where he can pilot the Aion Type-α against them. The energies make the Aion nigh invincible, but F. Novartis disables the robot after the fight and forces Dieter to rematerialize, citing the contract Mariabell Crois signed in his behalf to recover the Aions for Ouroboros.

2	All sepith ×200	Zeit was going to be the CPD's new mascot, but they wanted him to wear a hat and trenchcoat and say the catchphrase, 'Take a Zeit out of crime.'
3	Tempest Gown	I also received the gift of the Sept-Terrion. There was a second item, but I used spatial annihilation to keep you from getting it.
4	Celestial Balm EX	If a music group were to perform in this tower, would that make them an Orchistra?

Trails of Cold Steel IV[]

Background[]

After the events at the Gral of Erebos, a party consisting of Estelle and Joshua Bright, Renne, Lloyd Bannings, Elie MacDowell and KeA infiltrate the sector to find out what had happened in Heimdallr. They had traced some data that had been sent to the terminal (unknowingly by Black Alberich's request). As the sector was largely deactivated, navigating it was not difficult, although they still had to contend with some golems on the way. However, they were ambushed by Mariabell Crois, Alberich and Claire Rieveldt at the terminal. While Renne and KeA crack the five-dimensional spirit code the rest fight them off, leaving once they obtain the data, and learning about the beginning of the Great Twilight.

In their efforts to hold the third Rivalry, Rean Schwarzer's party infiltrate the Thaumaturgical Sector while the rest of the Radiant Wings hold an Arc en Ciel performance to divert the Imperial Defense Force's attention. Machias notes that the tower is once again gathering mana from nearby areas and channeling it to power the barrier deployed by the Society, and Randy additionally notes that the area is different from when he was here last during the independence.

With the sector now fully active, barriers and lift terminals that need to be disabled or bypassed and large numbers of golems are present. At the top, McBurn and a curse-driven Victor S. Arseid are waiting to defend the system. After Victor's defeat, Alberich deploys a Leviathan unit as additional insurance, but it's destroyed by Aurier Vander, Zechs Vander and Mueller Vander, allowing the rest to climb to the roof of the tower.
