The Fountain of Existence (存在の泉 Sonzai no Izumi ) refers to the vast amount of Power of Existence produced by the Whole Sacred Chapel, and may also refer to Misaki City once it has been fulfilled by the fountain.
Background[]
According to Bel-Peol of Bal Masqué, Crimson Lords have attempted to create Fountains of Existence in the past, but all of them failed.[1]
It was thought that all the power the fountain produced was consumed by the Manifestation of Alastor through Tenpa Jōsai, but a portion of the power was concealed and sealed underneath Misaki City by the isolation ability of the Treasure Tool Tartaros, and this portion was used as the energy source for the Statue of Pride.[2]
