The character seeks to achieve their goals without attracting attention.


Master Sin wants to achieve a world in perfect ecological balance.


According to legend, Master Sin was an alchemist and astronomer in the court of Queen Seondeok of Silla during the Three Kingdoms period of Korea. It was during his tenure in the court of Queen Seondeok that Master Sin first discovered the alchemical secret for arresting the aging process, a formula he has continued to refine and perfect. After the end of Queen Seondeok's reign, Master Sin formed the Jade Moon Society, a secret society dedicated to the pursuit of knowledge and the bringing into harmony of humanity and nature.

As the centuries passed, Master Sin's disappointment in humanity increased in proportion to his control of it. By the 12th century, his influence had spread to India and Persia, and by the end of the European colonial era his servants had infiltrated secret societies around the world, all secretly controlled by the Jade Moon Society. Master Sin's ultimate goal is a world in perfect ecological balance, but this fact is withheld from the Jade Moon's subordinate secret societies and their numerous front organizations. Only the fanatically loyal members of the Jade Moon Society itself are aware of this hidden agenda.

Powers and Abilities

Master Sin was born human, but his alchemical formulas and centuries of experience have given him intelligence and wisdom far beyond those he was born with. He has mastered most sciences and languages, and his thirst for knowledge ensures that no realm of human study is long neglected. His experience and keen intellect make him a formidable opponent. Given sufficient information, Master Sin is capable of predicting and preparing for nearly any eventuality. Many members of the Jade Moon Society believe that he can predict the future.

Physically, Master Sin is near the peak of human potential, and his rejuvenating elixir prevents him from aging and allows him to recover from nearly any injury. Despite his lack of more flamboyant abilities, Master Sin is one of the most dangerous people on Earth. His resources and his influence are both virtually unlimited.
