For years the Garde have fought the Mogadorians in secret. Now all of that has changed. The invasion has begun.

If the Garde can’t find a way to stop the Mogs, humanity will suffer the same fate as the Lorien: annihilation.

There is still hope. When the Elders sent the Garde to Earth, they had a plan-one which the Garde are finally starting to understand. A group of the Garde travelled to an ancient pyramid in Mexico known to their people as the Sanctuary. There they awoke a power that had been hidden within our planet for generations.

Now this power can save the world . . . or destroy it.

It will all depend on who wields it.
