Evacuation of Academy City

The Evacuation of Academy City was an event which occurred on December 12th in the current year of the story timeline.

Following Coronzon's attack on Aleister Crowley in the Windowless Building on December 11th, the latter took measures to prevent Academy City from falling into the demon's hands. Shutting down the city and locking its technology with a virus via the Bank, Aleister had the population evacuate to various locations around the world while personally seeking Coronzon's achilles heel in the United Kingdom, aiming to grasp it while the demon was temporarily sealed in Academy City.

Coronzon's Sealing
Early in the morning on December 12th, Coronzon managed to escape from the 'new world', dragging Nephthys and Niang-Niang along with her. She found herself in front of Heaven Canceller's Hospital and facing Aleister, whose consciousness had shifted to one of his diffused possibilities, a young girl. After revealing how she had sealed Academy City's technology, depriving the demon of its prize, Aleister sealed Coronzon temporarily using a city-scale Banner of the West.

Coronzon's Escape
While in London, Aleister encountered reproductions of the Golden Dawn, created by Coronzon as an anti-Crowley measure. Facing death at the hands of the reproduced Mathers, Aleister was forced to unlock Academy City's technology and fire a satellite laser to escape from Mathers' grasp. Shortly afterwards, Coronzon escaped from the seal and after fashioning herself a pair of wings from the 'contents' of spare parts from the Anti-Art Attachment, set off for the United Kingdom.
