After finding out she could never be a mother from the amount of magic within her at every waking moment of her life, Celestia hears the cries of a baby who looks only four months of age.
From where this creature comes, she does not know, but what she does know that this is a sign from the Wills that govern her world that the child to which she has named Zion, is to be her's. However a mystery hangs in the air as to why Zion is not a pony but a hairless ape instead.
Rated T due to the Birds and the Bees
