The Arcane Vault is one of the Outer [[Isemar Planes of Existence|Planes of Existence]]. The Arcane Vault is a vast, underground realm filled with endless corridors of stone and crystal, where hidden knowledge and forbidden secrets are stored. The air is thick with the hum of arcane energy, and every corner seems to hold some hidden mystery or ancient relic. The plane is a labyrinth of knowledge, with libraries that stretch for miles and vaults sealed with complex magical locks. **Inhabitants** The plane is guarded by enigmatic beings known as the Custodians, who protect the secrets stored within. [[Avaris]]'s most trusted followers—those who have proven their worth—are sometimes granted access to the plane to study its knowledge. However, those who seek forbidden knowledge without permission are often lost forever in its endless halls. **Notable Features** The Chamber of Forgotten Lore is the most secure area of the Vault, where the most dangerous and powerful secrets are kept. It is said that [[Avaris]] resides here, constantly sifting through the knowledge, deciding what should be revealed and what should remain hidden.
