St. Julian's Cathedral

St. Julian's Cathedral (ジュリアン大聖堂) is a cathedral of the Anglican Church, located in London.

Gleipnir
The cathedral is protected by a set of over thirty autonomous spiritual items, based off the dwarven-forged chain used to bind Fenrir until Ragnarok in Norse mythology and fashioned out of magically manufactured steel into a variety of animal-related shapes. These spiritual items will respond to the presence of an intruder and intercept them.

Background
At some point in the past, the current bishop was given his position as a reward for supplying personnel to Necessarius.
