Silver Water Holy Sea

The Silver Water Holy Sea (銀水聖海), simply known as the Silver Sea (銀海), is an area that encompasses many "worlds" or Silver Bubbles. Each world exists in a hierarchy, and the deeper the world, the stronger its order and the more powerful its inhabitants are.

Overview
The Silver Water Holy Sea is a vast sea of Silver Water (銀水), which absorbs magic power inexhaustibly. Because of this, life can only thrive inside bubbles that keep the water out. Countless of these Silver Bubbles are found in each of the Silver Sea's layers. The first to tenth layers are known as the Shallow Layer, the eleventh to twentieth are known as the Middle Layer, and the layers past the twentieth are known as the Deep Layer.

The deepest confirmed layer is the ninety-ninth one, but beyond that exists the "abyss of the Silver Sea" where the deepest world is at. This Abyssal World contains the Absolute Vortex (絶渦), or Maelstrom of Malice, a calamity in the Silver Sea that swallows everything, including small worlds.

Several Abysses (淵) also exist in the Silver Water Holy Sea, reservoirs for a certain kind of magical power that absorb people's thoughts and feelings. The Disaster Abyss of Craving in Evezeino is one of these, a place where all kinds of cravings are sucked in and swirl around as magical power. In the Listeria, the Forsaken Abyss of Remembrance collects the memories of the inhabitants of fallen worlds. Even if their host worlds were destroyed, the abysses will remain intact.
