Court astronomers first suspected its existence centuries ago, when the star the Emperor was born under suddenly vanished from the sky. Questioned, the baffled astronomers suggested it had been eaten by a pokemon from the heavenly sphere. Yet they did not follow up on this suspicion, for their concern was with the terribly bad omen it represented in their own realm; they did not understand that the disappearance of a single light meant that over a hundred suns had perished, and over a thousand worlds been left to freeze.

As much as those of us on earth emphasize the Sun and Moon, there is far greater power in the stars. Even a tiny shard of the crystals Necrozma has left behind can strengthen pokemon immensely – more than their bodies, or even their trainers, can withstand using multiple times in a single battle. It is difficult for worldly minds to even comprehend Necrozma's power, let alone to confront it, for what can someone so small do against a devourer of stars?

Yet Necrozma, too, is a pokemon in a sense, and there are many pokemon who only fight better in the dark. The world has its share of extrasolar power sources, even should it ignore our world and target our sun, and the people of Ultra Megalopolis have somehow, as of this writing, survived the destruction of that planet's home star.

It is true that Necrozma seeks to plunge our world into darkness, and I can only hope the inhabitants of Earth are clever enough to rise to this challenge. Interestingly, it is said that the stars Necrozma swallowed remain sealed within its body, and that Necrozma's true form is a light-bringer. But the power of light, in its own way, is even more terrifying than the power of darkness...
