Long ago, before the founding of Equestria between the Three Kingdoms, a particular Kingdom once existed. This was the First Kingdom, The Alicorns; members of ponykind that possessed all three types of magic. Magic of the body, magic of the wing, and magic of the horn. They were few, but grace spread wherever they cantered, and glory followed at their hooves. The latest in the line of Alicorns, Celestia and Luna, were cared for and loved by their mother and father as they became groomed to some day usher in a new era for ponykind; to unite them under one banner in the inevitable future.

Thousands of years later, in present day Equestria, after trials and tribulations aplenty, the two sisters of the sun and moon have done just that, despite the past returning to haunt their prosperity and tear their efforts asunder. Each adversary was met with the strength, values, and magic that bound the world, be it through powerful artifacts or through valiant hearts.

However, no matter the troubles, Celestia, the matriarch of the Sun, held anxious; paranoid for a threat far worse than everything they’ve faced combined. Something so horrible that it required the summoning of six extremely dangerous extra-equestrian beings to stand guard beside the Elements of Harmony. An event so catastrophic, that nothing short of the full force of harmony and chaos combined is needed to even hope to repel what’s to come. A repeat in history so monumental that it once resulted in the exact reason why Celestia and Luna were the last of their kind for so long.
