Apostles of Sephirah

The Apostles of Sephirah (セフィラの徒) are ten elves who are blessed with the ability to open the Shadow Palace.

Overview
The apostles are ten elves who represent spots on the Tree of Life monument and hold the special ability to open the Shadow Palace, a magical space between the realm of the living and the underworld. Because they are believed to be divinely blessed, the apostles serve as leaders among the Elf Tribe.

These ten are also more powerful than other elves and Magic Knight Captains.

Five centuries after the massacre of the Elf Tribe, the reincarnated apostles open the Shadow Palace in order to complete the Reincarnation Magic. However, a devil possesses one of the apostles and uses the eleventh magic stone to summon its own physical body from the underworld.

After the Reincarnation Magic is dispelled, only four apostles remain alive.
