Heart of Meridian

The Heart of Meridian, also known as the Heart of Metaworld or the Heart of Metamoor, is a long-lost magical crystal talisman in the shape of a tear drop that is actually the manifestion of the vast natural energies and magic of Metamoor.

History
The Heart of Meridian is one of the Hearts (including the Heart of Kandrakar), the rarest and most important artifacts of great power, and the very cores of the worlds within the W.I.T.C.H. universe.

The Heart also once worn by the royal family that ruled Meridian for generations before it disappears into obscurity during the time when the young Prince Phobos grew mad with power, stole the throne from his parents and corrupted the land with his powers.

The Heart of Meridian finally resurfaces after Phobos' long lost sister Elyon with the help of her friends who are the new Guardians, battled and defeated him and restored the entire realm of Metamoor to its true natural state in the season finale of the series' first season. In the beginning of the series' second season, the Heart was presented to Queen Elyon by a kitchen servant named Trill who said the crystal under the name Jewel of the Crown, belonged to her mother during the celebration of the Metaworld's freedom.

Later in the episode J is for Jewel, after easily and quickly defeating her vengeful brother Phobos during his raid on their family's castle, Elyon while saddened by the so-called truth about her mother and her father, throws the Heart of Meridian into Trill's hands. Then Trill laughs and was revealed to be the witch Nerissa whose sorcery interrupts the main function of the Palace's Chamber of Meditation, thus tricking Elyon into believing her birth parents were horrible people. When Elyon tried to make Nerissa pay for this treachery, she suddenly became trapped within her kingdom's very own treasure. Nerissa now has both Queen Elyon and the Heart of Meridian in her grasp.

Nerissa then incorporated the Heart of Meridian with the stolen Heart of Zamballa into her accursed sceptre known as the Seal of Nerissa.

In the season finale of the series' second season, Elyon was finally free along with others, reclaiming the Heart of Meridian and restoring her homeworld back to its original state.

Though Nerissa herself was unknowingly trapped in the Heart of Meridian and in a dream-like reality where she escaped her imprisonment, controls the fully-evolved Guardians and conquers the entire universe. She remains trapped there because unlike her former fellow prisoners, she chose power over harmony which in turn, became her ultimate downfall.

Powers and abilites

 * Generate waves and lightning bolts of energy and force.
 * Manipulate physical reality, changing it at will.
 * Create portals between Meridian and Earth, including ones that alter the matter that passes through (she was able to shrink the Guardians and Caleb when they traveled to Meridian through a portal Elyon created).
 * Open folds in space and in time to Earth, Meridan, Kandrakar, Zamballa, and other worlds.
