From a fan fiction where a being of cosmic power makes a bet with someone from our world about good vs evil. He chooses beings from the protagonists mind to represent the forces of evil such as; Jake Featherston from Harry Turtledove's Timeline 191 series. Azula from Avatar the Last Airbender. General Wilhelm Strasse "Deathshead," from Wolfenstein. Etc, and sets them down on the world of Two Kinds and accelerates time 5 years forward, then challenges the protagonist to choose from the forces of "good" to oppose them and free this world. The quote comes from General Deathshead after he and Jake Featherston tape captured Zen and Natani.
