Decoded Twilight Text

The True Believer is a newsletter the Twilight Hammer's disparate sects use to keep in touch. It is written and distributed by high-ranking members of the Twilight’s Hammer. The True Believer allows cultists to keep abreast of the latest signs of the apocalypse, and whatever else they consider news. The True Believer is encoded with a fiendishly difficult cipher. The only written key to the cipher, is the so-called Twilight Lexicon, which is split into three parts, each heavily guarded. The text that has been translated contains only the apocalyptic predictions of fanatical cultists.
