One of the top two strongest at the Regent Level, as well as a general under the Red Moon King. He was also the older brother of Baylon, the first Royal Star, and one of the victims destined to be sacrificed in the Battle of Ice Age.

The entire Energy Machinist organization was long broken up before this. After Mother Planet was defeated by the strongest White King, the Three Major Metropolis were massacred, only a limited amount of resources and a few lucky ones survived. The entire Energy Machinist had yet to recover from the setback.
