You were the only son, and heir, of the Arcadian king. But, to the king's disappointment, you were born with a weak body and fragile health... The king was ashamed of you, so he wouldn't let you leave the castle.

One day, the king, your father, took you to the royal magicians... You thought he was after something to make your body healthy and strong, but the truth was much worse... He was looking for a way to create a replacement for you...

When you were about to turn 18 he was created, Allen... A clone created from an ancient and powerful magic, he was the exact copy of you... Eyes, hair and face, everything was the same... The only difference was that Allen's body was strong, as was his health...

Allen had been raised to be your replacement, since your father didn't want you to become the next king... The clone then became the king's new "son", and you remained locked inside the castle...

Allen could do everything you never could, it made your heart feel bitter...
