In order to save face for the organizations and individuals involved, the truth of the Frontier Incident was swept entirely under the rug.
As a fundamental part of those events, John Wayne Vercingetorix (aka Dr. Ver) was not given a trial in a court of law, but rather locked away in the Dragon Shrine in the abyss under the pretense that he wasn’t human, but rather a part of the dangerous complete relic known as the “Nephilim.”
His left arm and the power of the Nephilim that resides inside of it, remain perfectly functional. It still retains the ability to consume, assimilate, and control other relics.
However, there is a sharp downside to that incredible ability in that it has absolutely no effect on any power or device that is not derived from a relic at its source. For this reason, Dr. Ver's isolated cell was constructed almost exactly the same as those in a common prison.
