A hundred years ago after the death of the son of Lord Seth Kin, Rion Kin, a prophecy was made by the grandmaster of vision who was known as the 'Emerald's eye'.
He said, "Upon night when the red awakens and the green shall form the Rombus."
The Rombus was a pearl in the form of a soul formed from green magic. In Panacea, not all immortals were destined to reincarnate. Only the destined ones were reincarnated and the destined ones were chosen by the Rombus. The Emerald's eye prophesied that Lord Seth's son was a destined immortal and hence his soul would be reborn. However, he didn't mention it in further detail as he claimed that he couldn't foresee beyond the realm barrier.
