Bisartan the Secretary was a popular hero of the Bahari peoples dating back to Ancient Bulwar.
According to the tablets that survived in Aqatbar's library, Birsartan heard the news of Surael's truth and went to Eduz-Vacyn to become Hammura's personal scribe. After the death of his master, he became the second Kašra of Eduz-Vacyn and established the bureaucratic aspects of the Sun Cult. Later in his life he went back to Bahar where he managed to convert the local kings to the Cult of Surael.
He died in a small temple he had build near the Našra river and was buried beneath it. This pilgrimage site later became the town of Birsartansbar.
