Mercury :
Many people think that when we are the guardian - or apprentice guardian - of a star like the Moon, we are forced to remain living among the stars, in the form of a spectral being, living well beyond what humanity could see. Yet, it is not uncommon for these entities to settle on Earth or any other planet, before taking on a similar appearance to the local inhabitants and beginning to live on the chosen planet, while continuing their work. This allows these creatures to learn more about the modern world, and to work even better.
One evening, as the Moon was shining from its crescent shape in the sky, a star near it seemed to twinkle even brighter than usual. The little star then began to fall from the sky, like a shooting star, and fell to Earth in a mass of dust. Asleep in the heart of the crater that the star had formed, was a mysterious black and white wolf, who seemed to enjoy absorbing the lunar rays nearby.
Looks like he will be waking up soon...
