The spiritual leaders of Nocturne are known as the Abbots, but even higher still is the High Abbot, a single person who sits at the lowest levels of the Abyss and has devoted their life in service to Void. He serves as the mortal voice of Void and relay the wishes of Void to all the Clusters via the Abbots.

The Abyss is a multilayered plane of existence considered to be the most holy place for all Nocturnians. Entrance to this plane is only accessible via several massive caves woven from branch and bramble scattered throughout the wilderness. The original castle architects were drawn to the Abyss Gates because of the infectious aura that they produce.
