The Pavilion[edit]
The Pavilion is the magnum opus of the Witch King's Arts in his later years. It is a giant fortification inside the Aetherside that had been constantly preventing the Collapsals from invading realspace. The Pavilion preserved all the historical buildings in Leithanian history, acting as eternal symbols of the empire. The Witch King believed that it was not built by himself, but by the essence of the whole of humanity and their civilizations. He envisioned the Pavilion to be an eternal monument within the Aetherside where aftercomers would follow.[2]
By the time of the Stimmverlust, the Pavilion was on the verge of collapse as the Witch King could no longer withstand the corrupting force of the Collapsals. Many of the structures gradually crumbled due to his weakening strength. Furthermore, the final battle between the Witch King and the Twin Empresses brought more damage to the building. After the defeat, Fremont "banished" both his soul and the Pavilion altogether to eradicate his influence on the nation once and for all, and the Pavilion was instead replaced by Empress Hildegard's newly built Spire.
