To prevent Prince Phobos' evil plans from spreading beyond the world of Metamoor and to protect the rest of the universe, the Oracle lowered a Veil over the planet, separating Metamoor from the rest of the realms under Kandrakar’s protection. However, several portals have opened between Meridian and Heatherfield on Earth, creating a series of passageways for the desperate refugees and monsters of Meridian to infiltrate Earth. The Portals weaken the Veil and to prevent this, generations of Guardians were sent to protect it from collapsing.
