Origin of the Runelords
Thassilon was founded more than 11,000 years ago by First King Xin who had been exiled from his homeland of Azlant for promoting heretical beliefs. As the empire grew beyond the bounds of Xin's ability to control, both militarily and administratively, he appointed powerful arcanists as governors to oversee his lands. The mightiest of these were the runelords, seven of the most skilled (and power-hungry) wizards in Thassilon, if not all of Golarion. Working secretly to secure power for themselves, the opportunity to fully escape servitude under First King Xin appeared when he, in his old age and after having ruled Thassilon for more than a century, destroyed himself and much of his palace in a mysterious magical event. The runelords seized the opportunity and subjugated those loyal to Xin – including his own son, who became a puppet emperor – while each plotted within his or her own lands to become ruler of all Thassilon.
