The One, and Only, Royal

The black moon holds the key,
The only one to know shall be she.
Her rule will bring peace to all,
Or into chaos the world will fall.
Her mate will begin the war,
Of sacrifices, she must make four.
For she is the one, and only, royal.

The prophecy has been known since the first living werewolves and no one knows the true meaning of it. Very few believed it would ever come true. That is until the "royal" is born. Only her pack knows she exists. They know they need to hide her, keep her safe. So what happens when she finds her mate, and the prophecy begins to unravel?
