Power of The Twice-Blessed Children

The Prophecy of the Twice-Blessed Child is an ancient prophecy decribing the birth of a child holding great magical power and wisdom. If nurtured properly, the child would become a savior of the world; but if he falls under the influence of evil, he will become the world's ultimate destroyer.

The Prophecy

 * When three planets burn as one
 * over a sky of dancing light,
 * Magic will rest on a holy day
 * to welcome a twice blessed child. 

History
Arrival The quatrain decribing the prophecy was unearthed by Merrill, a powerful wizard and mentor of Cronyn. He reasoned that the baby was to be born to Piper Halliwell and Leo Wyatt, a witch and whitelighter respectively.

Merrill knew that the child would be born when magic rested on a holy wiccan day. His former pupil Cronyn and the demon Doris planned to obtain the child to raise it as evil. On the wiccan sabbath Imbolc, which fell on the same day as the Aurora Borealis, Piper went into labor. After the sorcerer and his demons were vanquished, her sisters helped her give birth to Wyatt Halliwell, the twice-blessed child.

Altering the Prophecy
"The Elders hoped to alter the prophecy of the Twice-Blessed. That the firstborn children of the family would inherit the Power of Three. Making Wyatt, Chris, and Melinda an even more powerful force for good than the Charmed Ones."

- Kyle to Leo and Paige.

In 2008, the third child of Piper and Leo, Melinda Halliwell displayed the power to orb, despite the fact that Leo was mortal during her conception.

As they searched for answers, Kyle Brody revealed to Leo that the former Council of Elders altered the prophecy to make all three of his children twice-blessed. This went as far as bringing out his dormant Whitelighter DNA in Melinda. The reason they did this was to ensure that the oldest of the Charmed Ones' children would inherit the Power of Three and become a great force of good akin to the Charmed Ones.

Erasing the Prophecy
After the battle against Neena, the Angels of Destiny realized the errors of tampering with people's lives and destinies. As a result, the Angels absolved the twice-blessed children of their status, negating the prophecy and absolving them of any future callings.

Recalling the Prophecy
After both Wyatt, Chris and Melinda had turned 21, the prophecy reappeared. A new, huge threat had been foreseen, and the Elders needed for The Charmed Ones to exist again.

Notes and Trivia

 * In The Heir Up There, Kyle Brody specifically mentions that Twice-Blessed means being the child of a Charmed One and a Whitelighter.
