Birthnight

Short story of 7k words
On the night that Christ was born, he received many visitors, and among those, unchronicled, the vast host of the legendary creatures who still roamed the world: the dragon, the unicorn, the phoenix, and the Queen of all Faerie, to name only a few.
The immortals were called by a strange, unknown constellation, drawn to the child whose birth would herald the start of a new age—and the end of an old one.
