From the back of the book:
Peace after a century of war, we began to rebuild the world, we looked to the stars to see our destiny. We did not dream they were looking back.
The Invasion came swift, without mercy, they saw only a world broken by endless conflict, but they reckoned without the Chosen. Unbowed, Unbroken, Undefeated.
We will drive them back and discover anew what the wars took from us, for this is our world, this is our... Quest.
From the book:
Quest uses six-sided dice for all Skill and Attribute tests, with the number of dice used dictated by the test being taken.
