Osgiliath Basin 1 (Sen IV)

Osgiliath Basin (オズギリアス盆地), also known as the Forbidden Land (禁忌の地), is a depression in the central north of Erebonia.

Background[]

In the past, Osgiliath Basin was the battlefield between Erebonia's two Sept-Terrions. Due to the ensuing fight between Ark Rouge and Lost Zem, both Sept-Terrions became empty shells when their clash created The Divine Knights and Osgiliath Basin was formed from the damage caused by them.

The lamp-shaped artifact Eternal Kandelaar, capable of introducing higher elementals to a specific area, was found during an excavation in Osgiliath Basin.[1][2] It was immediately brought to the Imperial Museum in the Leica District, Heimdallr.

Background[]

During the events of the Great Twilight, Class VII traveled to Osgiliath Basin to place a spirit stake in it, in order to locate the Black Workshop and rescue their instructor Rean Schwarzer. While there, they receive a message sent by their classmate Musse Egret and meet up with her and Aurelia Le Guin to inform the of her motives for joining Class VII and creating the Weissland Army.

After her classmates convince her to come back and help them however, they are surrounded by the Thors Military Academy main campus and the Red Constellation led by prince Cedric Reise Arnor with Michael Irving now an instructor for the main campus and Shirley Orlando a student. While they attempt to arrest them and hold Aurelia in position with a sniper aimed at her, Class VII manages to defeat them in battle and Cedric calls on Testa-Rossa to take them out. Thanks to the use of their Panzer Soldats, they defeat Testa-Rossa as well and the Weissland Army arrives to help drive off the Main Campus and the Red Constellation Jaegers.

After the fight, Class VII places the item in the Basin and decide to return to Eryn. Due to Musse rejoining Class VII, she leaves Aurelia in charge of the Weissland Army in her place.

Following the rescue of Rean Schwarzer, Class VII return to Osgiliath Basin and find Beryl there as well. She hints at the Basin being the battlefield between the two Sept-Terrions in the past and tell the group that she senses a powerful Cryptid in the Basin and that defeating it might reward them.

Following Arianrhod's Rivalry and death at the hands of Rufus Albarea, Tuatha De Danann emerges from a pocket of space above Osgiliath Basin and is transported to Heimdallr by Black Alberich, Giliath Osborne and the Ironbloods to serve as the stage for the final Rivalries. To ensure Class VII couldn't enter immediately so the conflict could enhance the Rivalries, five Salt Pales similar to the one that destroyed North Ambria appeared all over Erebonia and acted as part of a barrier protecting Tuatha De Danann.
