Imprisonment
It did not take long for the god-king to find and trap his brother. Even in its weaken state the Fay empire was powerful and far reaching. But having caught his brother, there now was a dilemma.
To kill a Fay, the place from which the spirit originated must be destroyed. Physically eradicating the twin's birthplace was not a problem for a god-king who could destroy planets but they were twins. They shared the same origin. Destroying his younger brother would mean destroying himself.
Instead, the elder brother devised a prison.
The plain box that had contained the source to their problems was fitted with a tiny gold lock. The younger brother was stripped of his physical form and his spirit placed into the box. The box was then placed in a stone sarcophagus that in turn was locked. Magic bound everything closed, making them impossible to open.
The younger brother would have spent the rest of eternity imprisoned except for one small mistake. Unwilling to do anything himself, the elder brother used a human slave to lock the wooden box. Unfortunately for the god-king, the slave was not all he appeared.
The slave had long been the elder brother's personal servant. He was in the room, taken for granted like a piece of furniture, when the box was first open. He was the first to be infected and his self-awareness came suddenly and fully but he did not react. He did not reveal himself as being infected and continued to serve the elder brother.
As the slave shut the wooden box containing the spirit of the younger brother, the spirit of the person who had given life to him and all his people, he opened his mind. A small part of the spirit entered the slave. Whilst most of the younger brothers spirit was trapped for all eternity, a small part was free. Free to travel, free to watch the chaos he had unleashed, free to seek someone capable of releasing his spirit from his brother's prison.
To the other Fay who believe that the twin is sealed in his tomb, the younger brother was the destroyer of their civilisation. On the sarcophagus is inscribed:
“The Cursed One. The bringer of ruin, destroyer of the Fay, home-wrecker, traitor, cheat. Thrice dammed nightmare, destroyer of worlds, taker of souls, ravager of cities, plunderer of children, bringer of chaos. Life Stealer”
