Heart of Kandrakar

The Heart of Kandrakar (or Heart of Candracar), is a fictional magical pendant from the Italian W.I.T.C.H. comic book and the French animated series of the same name. It is bestowed to the leader of the Guardians of the Veil, and enables the Guardians to transform into their superhero alter egos by channeling the power of the Aurameres into them.

Although the Guardians have some power without the Heart, their strength is greatly increased by it. Without it, the Guardians' powers would be drawn from their life force instead of the Aurameres.

In the comic book, the Heart is a unique magical jewel that merges with its holder's body when it is not in use, and retains a shade of them when it is passed on to the next holder. In the animated series, the Heart remains distinct from its owner, and each world had a Heart of its own. Some of which are jewels like the Heart of Kandrakar, and others of which are people with tremendous magical power. In Season 2, it is revealed that Elyon is the Heart of Meridian, and Lillian Hale is the Heart of Earth. It is also revealed that the holder of one Heart can merge it with another world's Heart, but only if that Heart is given willingly. However, the Hearts of each world cannot be taken by force. They must be given willingly, which is why Nerissa had to resort to trickery to acquire Elyon's powers instead of direct confrontation or stealing it from her. This means that the Heart of Kandrakar is literally the "Heart" of Kandrakar, and possibly its central power source, or perhaps vice versa. In the comic book, the Heart is the symbol of Kandrakar, which explains the reason the Oracle's head is marked with its symbol. Also, even the Oracle does not have the power to demand the Keeper hand it over, and the Keeper must decide to return it, which is the reason why Endarno does not simply use his powers as the new Oracle to take the Heart from Will, which would enable him to succeed in his evil scheme and greatly weaken the Guardians.
