Od Lagna

**Od Lagna** (オド・ラグナ, *Odo Raguna*) is a reserve of mana that is considered to be the heart of the world.

## Information

Any kind of concrete knowledge regarding Od Lagna is generally minimal for most people in the world, including among accomplished magic users. Its exact location is unknown. If the world itself were to be considered a living creature, Od Lagna would be the Od of the world. Throughout history, various genius mages who utilized forbidden magic somehow saw Od Lagna, a mass of mana unlike anything they had seen before, and eventually lost their minds. Some speculate that it is a consciousness that rules over everything in the world; others believe it is responsible for bestowing Divine Protections to people.

According to the author, Od Lagna is not a lifeform with a will, so it is not hostile to anyone, much like the sun. It is considered as the heart of the world, where all mana eventually returns to. To some extent, it can bestow Divine Protections. For example, it can create Divine Protections and give them to Reinhard van Astrea when he feels they are needed, but he may not receive a proper one if there is an error in conveying his intention. Furthermore, Od Lagna also gives life to spirits and births them as lesser spirits.

Rui Arneb concludes that Od Lagna has no ideology and is merely a mechanism responsible for keeping the world from breaking. It is impartial, does not favor anything, and can not understand people's hearts. In addition, it is the antithesis of Witch Factors.

### Corridor of Memories

The **Corridor of Memories** (記憶の回廊, *Kioku no Kairō*) is the cradle of Od Lagna. It is a white expanse that is the resting place of the souls of the dead and where they go to commence the process of being filtered. When a soul is filtered, the memories attached to it are cleared off like dirt, allowing for its reuse once it becomes clean. The memories of the soul are then sent to the library at the Pleiades Watchtower, where they are used to create a Book of the Dead, which contains the history of the soul's life.

Rui Arneb resided within the Corridor of Memories from her birth, up until the events of Arc 6. She was familiar with the place, having gained her knowledge about it from the memories she accumulated through her Authority. Rui claimed that happenings within the Corridor of Memories could not leak to the outside easily, not even being able to reach Satella. Moreover, she had some degree of limited control over it, being able to beckon it to remove someone from there. Rui could not completely control it, however, as she only had the capability to interfere in its processes by using the Authority of Gluttony. According to a hypothesis made by Natsuki Subaru, Flugel may be the Corridor of Memories' ruler.

## Trivia

* If it were necessary, Reinhard could defeat Od Lagna if he fought it.
* It has been stated that the world itself will not allow Reinhard to die. It is not known if Od Lagna has specifically chosen to keep him alive, or if an external force is responsible.
* The Authority of Wrath held by the Witch of Wrath, Minerva, directly linked her to Od Lagna. It could forcibly convert her destructive energy into healing power, but because it twisted the rules of Od Lagna, this came at the cost of creating natural disasters that wreaked havoc in other parts of the world.

And because of that, the world was forced to pay its due compensation for having twisted its general notions, in the shape of a natural disaster somewhere completely unrelated.* The Witch's After Tea Party / The Requirements to be a Witch, Section 2.
