The twins each possessed such powerful magic that when together, their combined magic rivaled that of the Soverigns.

It was believed twins bring about sorrow, unhappiness, ruin to their parents... the country would be next, but to kill them would bring even greater devastation. People feared that when the twins reached maturiy they would take over the throne. To prevent that and further calamity on the country, the Soverign sentenced them to be imprisoned in a valley where magic was usless and time flowed at a different pace. The only way for them to avoid the sentance was for one of them to die. But silently, both twins chose to life and one (Fai) was imprisoned at the top of the valley's tower while the other (Yûhi) sat outside at the bottom. There they would stay until the world itself came to an end.

The Curse

The Soverign also cursed the twins, for their bodies and the calamity that they bring would be sealed away. Twins were damned to sorrow, their magic guaranteeing a lifelong damnation since birth. The more sorrow and pain they felt, the greater the country and its people's happiness would prosper.

The Valley

A place where the guilty are cast, undeserving to lie safely in a grave. In the valley, nothing decays but stays in the same condition as when it was thrown in. People believed that was the future the guilty deserved.

Yûhi & Fai

Yûhi
Outside, Yûhi began piling the dead bodies around him against the side of the tower trying to make a make-shift ladder to reach Fai.

After his brother's death, he took his name, forsaking his own. Thus Yûhi became "Fai".

Became Fei-Wong Reed's trump card, protecting the Princess of Clow from harm so Fei-Wong's plan could be fulfilled.

Fai
Inside the tower, Fai could only watch Yûhi struggle to reach him. After the Soverign's death, he began to wish for his own, so Yûhi would be set free of the curse.

The End

After some time, Yûhi noticed more and more young and old people, innocent, were being thrown into the valley. One body happened to be holding a scroll which revealed that in fits of insanity the Soverign had started putting innocent people to death. No one could stop him all they could do was beg for foreign armies to help them. And the blame for it all rested on the twin princes.

Eventually the Soverign himself fell down to the valley, the only one left from Valeria except the twins. Blaming them, he killed himself in front of Yûhi, leaving them to sole survivors, forcing them to live and attempt to atone for their guilt.

The Price

Fei-Wong Reed appeared to each of the twins, offering to free one of the them; the other would die. Wanting desperately to save his twin, Fai told him to free Yûhi, causing him to be thrown from the tower down to the ground, dead, his memories tranferring to Yûhi. Fei-Wong then cursed Yûhi to live with the responsibility of his brother's death, however he also offered him a chance to bring Fai back to life, if he did something for him.
