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 manifestation 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.

It was once worn by the royal family for years while they that ruled Meridian before it disappeared into obscurity when the young Prince Phobos grew mad with power, stole the throne and corrupted the land with his powers. When Phobos' sister Elyon defeated him with the help of the new Guardians and restored the realm of Metamoor to its true natural state the Heart reappeared.

[Nerissa stole and used it to trap Elyon within her kingdom's very own treasure. She then combined it with the Heart of Zamballa into her accursed sceptre known as the Seal of Nerissa. Elyon was finally free along with other former guardians, though Nerissa herself was trapped in the Heart in a dream-like reality where she escaped her imprisonment, controls the fully-evolved Guardians and conquers the entire universe. Elyon reclaimed the Heart of Meridian and restored her homeworld back to normal.

Powers and abilities

 * 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.
 * Generate ghostly images of herself, similar to the Astral Drops. These illusionary copies are capable of moving independently of Elyon, but have no shadows, nor do they react as a real person would. If they are touched ,they disappear.
