The Jydan Writings was a religious text of the Jydan religion and its derivative, Ni'Shaw-Dak religion.
The Jydan Writings told of the beginning of time and the galaxy being ruled by the gods. The gods, upon the Writings, favored the Ka'hren species.
The Jydan Writings included the teachings of the multiple Jydan gods, written by the three prophets of each individual god (as opposed to the other holy text of Jydan, the Volumes of Truth, also written by the three prophets of each god but telling the god's laws and ethics).
