Zerahtara[]
The Zerahtara is an ancient book that the followers of Duaess study. It speaks of Ostiran and the Ancient Ones (of which only Enuch and Negatron are named), as well as the five sects of magic and how to use them. It defines specific spells of each sect, some of which may take years to learn.
Originally, there was only one copy of the Zerahtara, but later the followers of Duaess fabricated many more. There are now special scribes called Zuhar, devoted to making copies of the Zerahtara and other religious documents. The first Zerahtara still exists today, but is kept as well preserved as possible and is not used anymore. It kept in a special building in the city of Thaerul, which is highly populated by Duaess followers.
