According to Jistkan hagiography, Arustun and his older brother Ejanos rediscovered the Azlanti treasures in the Cave of Tiandra in approximately -4160 AR. Ejanos wanted to burn the strange scrolls as fuel but Arustun, knowing that these relics were important, contested his brother's claim to them and inadvertently killed him. With Ejanos' death, Arustun suddenly gained the ability to understand the writings and quickly absorbed these sparse treasures of Azlanti lore while in the cave.
Arustun, with his wife Mirnura and his friend Venistos, crafted a ship for himself and his favored companions and traveled the Inner Sea for years from shore to shore searching for knowledge that could enhance what he had learned from the Azlanti relics in the Cave of Tiandra. His travels took him far across the lands of Avistan and Garund, from the shadow-bound warrior-lords of ancient Nidal to the magnificent Sky Citadels of the dwarves. Arustun recruited numerous allies in his quest of civilization and recorded everything he saw and learned in his extensive journals, later to be collectively known as the Poleiheira. After his journeys around the Inner Sea, Arustun—using the forgotten magic of fallen Azlant and Thassilon that he had learned—managed to travel the planes, most notably the Eternal City of Axis. While he was in Axis, Arustun finalized his plans to found the empire he envisioned.
He returned home from his odyssey in -4120 AR with many foreign associates and allies. He founded the Jistka Imperium in northwestern Garund and named the capital after his beloved wife, who had remained behind for all the years of his absence helping their people.
