We were counting the moon, perhaps it will show is the way to where the baby is, the constellation were aligning, full of sign and meaning of a new child born in a far place. The curiosity will make the wise men search for the sign.
As they count each step closer the star moved, aligning once again, resetting it self like a map, telling of the journey to take to the delivery room of a child, for that was what the star said, that's what it shows : A child.
There won't be any star like this for centuries, or never will we see such a star.
