Sephira Crystal



Sephira Crystals are mysterious, round, orb-like gems that contain Angels, can turn humans and non-humans into Spirits and serve as the power source of their Spirit Form. They also have alternate forms called  Qlipha Crystals that contain Demon Kings and serve as the power source of the Spirits' Inverse Forms.

Bonding
In order for a Sephira Crystal to turn a human into a Spirit, they simply need to touch it. The gem is then absorbed into the one who touched it and will turn that person into a Spirit.

Removal
So far, there have shown to be three ways for a Sephira Crystal can be removed from a Spirits' body. The first method is to kill the Spirit. Finally, Artemishia has also shown the ability to remove a Qlipha Crystal through unknown means by using her territory. By removing the Qlipha Crystal, Eckidina KnightWalker put the Crystal in her chest and became Diabla the Qliphoth Tyrant, a Inverse Form of her original self.

Trivia

 * The Sephira Crystals are named after the Sephirot Tree, the tree that the Spirits are based off of.
 * Since each Sephira Crystal contains an Angel inside of it, the powers of a Spirit may come from the Angels themselves and the body is simply acting as a host for manifesting the Angel's power.
