Gleipnir (グレイプニル?) is a set of spiritual items, crafted by Ellasone and based off the dwarven-forged chain which was used to bind Fenrir until Ragnarok in Norse mythology, which are used to protect St. Julian's Cathedral.



Gleipnir is a set of over thirty autonomous spiritual items, which react to intruders and intercept them. They are made out of magically manufactured steel and crafted into a number of giant animal-related shapes, including snakes, octopuses and bats. The metal snakes are over 15cm thick and over 5m long, capable of crushing marble pillars when wrapped around them.[1]
