 "You find life such a problem because you think there are good people and bad people. You're wrong, of course. There are, always and only, the bad people, but some of them are on opposite sides." 
 --Terry Pratchett 
 Summon up your own shadow and let it pull you into the Twilight, the liminal land of heartless greys and mysterious shadows, where truths cannot be hidden and where magic is real. But the Twilight's gift is two-edged. While it will grant you powers, it will also leech away your humanity, transforming you into an Other: an inhuman, immortal being who sees the world as inalterably divided into Light and Dark. If you walk into the Twilight, pray that you do so with a merry heart. Don't bring anger or greed or sadness, because that first moment in the Twilight will alter your fate forever. Walk in with laughter on your lips and you'll be a servant of the Light; step in with sadness and you'll be a creature of the Dark.
