Twilight Keepers

Some of the Twilight's Hammer cult members carry around little papers with gibberish written on them. To decipher them, a book is used by their scribes to encode secret messages: the Twilight Lexicon. It's such an important tool that they keep its three chapters in different locations. Mayna, Havunth, and Exeter are the keepers of them and are known as the Twilight Keepers.
