Powers and Abilities
The R-System or "Resurrection-System" can bring anyone who's deceased back to life. However, there's a high cost to the process. To complete the operation, an enormous amount of 2.7 Billion Edeas is required. That kind of power can be produced by the Etherion, a Magic weapon of mass destruction owned by the Magic Council. After getting the energy it needs, the tower will transform into its complete form: a giant blue Lacrima crystal. However, it still won't be activated it receives a human sacrifice. The person must have Magic Power close to the level of the Ten Wizard Saints. The body of the person is then fused with the Lacriman and is broken down and remodeled into the body of the very person the System is meant to revive.
