In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.

They were driven out by an implacable enemy, something beyond their understanding…and ours.

Many of us know that the Moon pulls on our oceans, driving the tides, but did you know that it smells like gunpowder? Or that it was essential to the development of science and religion?

The battle lines are collapsing, and the Legion of Wolves cannot hold back the tide. Luna and Earth are both falling to the enemy, and there is little hope as the defense is pushed back on all sides.
