In all our history Humanity has made stories that can only be described as fiction; wizards throwing fireballs, swordsmen slicing mountains apart, space explorers facillitating peace between galaxy-spanning empires, men and women standing against an unbreakable tide and winning. We know these stories to be false, written for our enjoyment and inspiration, but they don't. The Wardens of Life, that's how it translates to our language, have fought a losing war against a species of alien they call Scourge. The Wardens found our world, found our stories, and rejoiced; on this planet resided a species of sword-slashing, gun-toting, fire-flinging warriors. A species that rejoiced in our history and was the answer to all of their desperate hopes. Now we have to try not to disappoint their hopes.
