Rebirth and Explanations

After a tragic Accident, Parity, the spirit of Balance, was unable to hold his physical form and was temporarily destroyed, leaving his two students, Lumiere (Spirit of Positivity) and Foncene (Spirit of Negativity), to keep the balance in all of reality.

When he finally returns 5,000 years later, he has to react to the events of "Rise of the Guardians" and his students' failure.

This can't end well...
