Those who Know the Rune of the God’s Sword

Those who Know the Rune of the God’s Sword (神の剣の文字を知る者) was a Norse Magic Cabal, one of five who united to attack Brunhild Eiktobel's cabal and were subsequently destroyed by her in revenge.

Principles
The cabal apparently specializes in large scale spiritual items.

Their base is a giant wooden ship, located on a flat asphalt area at a harbor on an artificial waterway cut into the land. It is over 30 metres long and the bottom curves up in a half-circle - the gap between it and the ground is filled by dozens of wooden pillars. The outer walls of the boat are fortified with various barriers and defensive spells. Their assets are concentrated in this one base, as opposed to modern magic cabals who split their assets between multiple bases to minimize losses should one be lost.

Background
Five years ago, Those who Know the Rune of the God’s Sword, together with Those Who Prevent the Extermination of the World Tree, the Iron Stake that Carves Knowledge, Champions from the Sea and the Hammer that Tempers Gold within the Earth, attacked Brunhild Eiktobel's cabal out of fear that her nature as a Saint and Valkyrie would cause pure Norse-style magic to go into decline.

Toaru Majutsu no Index SS: Kanzaki
Those who Know the Rune of the God’s Sword was noted to have been active recently by the Tour Guide, around the time of the bombings carried out by the magician Leasic.

During the attacks on various Norse cabals by Brunhild Eiktobel, knowing that they were being targeted in order of danger, Kanzaki Kaori went to the base of Those who Know the Rune of God's Sword ahead of the attacker. Being briefly mistaken for Brunhild on arrival, Kanzaki quickly dealt with the cabal and evicted them from their base.

The cabal members were taken away by a Necessarius recovery team (and also taken in for the various things they were guilty of), while Kanzaki made preparations for the attacker's arrival at the base. However Brunhild attacked the cabal members and the recovery team, believing the latter to be reinforcements. Throwing a number of them as human cannonballs at the base, she briefly clashed with Kanzaki but decided to withdraw, their clash destroying the pillars below the boat and causing it to roll over.

Survivors from the cabal and the retrieval team were later taken to a Necessarius hideout for treatment. Cabal members were left with their arms and legs broken as well one eye and part of an organ crushed. They also had healing-inhibiting runes carved inside their lungs.
