Levyngilma

Levyngilma, the Sword of the Almighty (全能者の剣リヴァインギルマ) is a divine sword created by Arcana's divine power.

Appearance
Levyngilma takes the shape of a silver divine sword.

Selection Trial Arc
After Arcana obtained the holy sword Evansmana, which Ahid stole from Lay due to Arcana's divine authority, and Shin's demon sword Gneodoros, which she took from him during their battle, she used them in conjunction with Artieltonoa, the Moon of Creation, to combine them into Levyngilma. Due to the sword's permanence effect, Ahid was rendered immortal and couldn't be destroyed by Anos. She stated that Anos would only be able to destroy him by drawing Levyngilma from its sheath and slashing Ahid thrice with it but that Anos' source would be erased as a result of drawing the sword. Eventually, Anos activated Veneziara to allow himself to draw the sword without destroying his source, as he slashed Ahid with it and removed his borrowed divine power, defeating him.

When questioned by Anos, Arcana stated that she created Levyngilma as a trial to find someone worthy of becoming an agent. They must realize that an Almighty being does not exist because if an Almighty being cannot create a sword that they cannot draw, they are not Almighty, but if they cannot draw a sword that cannot be drawn, they are not almighty either. However, Anos was able to give a different answer to Arcana's trial. He realized the possibility of drawing and not drawing the sword from its sheath simultaneously using Veneziara, thereby keeping his source safe and allowing him to wield Levyngilma.

Abilities

 * Eternal Permanence: When the sword is summoned, the person who formed a pact with Arcana will remain in a state of permanence and cannot be destroyed. Regardless of what power is used to attack them, the pact holder will remain unharmed as they aren't subject to any forms of destruction.
 * Absolute Severance: Levyngilma is the only means of harming the one who was granted eternal permanence from the sword, as the permanence can removed if they slashed thrice with the sword. The true power of this weapon is that it can cut through anything, no matter how indestructible it may be, including the gods, even those that have abilities that make them immortal such as God of Traces Rivershned, whose order of traces makes them eternal so long as the past exists.

Weaknesses

 * Source Erasure: If one were to draw Levyngilma from its sheath, the divine power of the sword would erase the source of the one who drew it in the past, present, and future, thus erasing them from existence throughout all of time. Even source regeneration magic spells like Agronemt wouldn't be able to restore the source. However, it was shown to be possible to circumvent the sword's negative effect in various ways, such as Anos using Veneziara, by allowing the possibility of drawing the sword and not drawing the sword into reality at the same time.

Trivia

 * Arcana's question of "Can the almighty one create a sword that no one can draw?" is a variation of the omnipotence paradox.
