The ancient empire of Thassilon (pronounced THAH-sih-lon) occupied most of western Avistan for over a millennium. While its power was great, struggles for control within the nation itself tore Thassilon apart. All that now remains are mysterious ruined monoliths scattered throughout the landscape of Varisia.


The sprawling empire of Thassilon was powered by conquest and its sophisticated rune magic. That magic defi ned the empire’s rulers and included various forms of blood sacrifice, powerful glyph-laying, and dimensional warping. Without rune magic and the binding of the rune giants, the Thassilon legions would never have conquered their vast lands. With them, though, they were unstoppable.


Emperor Xin

Emperor Xin was a visionary who founded the vast and powerful empire of Thassilon. Though exact dates from this pre-Earthfall time are hard to gauge exactly, it is believed that Xin began the formation of the Thassilonian empire approximately eleven thousand years ago. He helped to create not only his empire but many orders of knights and wizards and is also credited with fostering monastic orders. His goal was to create a civilized paradise within his empire. To do this, Xin bargained with mighty and powerful creatures, ancient dragons and inscrutable outsiders. These creatures granted knowledge of rune magic, said by some to be the language of creation itself, and promoted the worship of the goddess Lissala. Xin used this knowledge in many aspects of day to day life within Thassilon. Xin lived longer than your average man, ruling until the age of one hundred and ten and his death was as exceptional as his life. Rather than succumbing to the ravages of age or disease he was consumed by his own magics which immolated him in crimson flames and destroyed much of his palace, leaving no remains whatsoever.

After his death the reign of the Runelords would secure their power.

Ways of the Empire

At its height, the Empire of Thassilon covered an area more than a thousand miles wide, from the oceans to soaring mountains, over deserts and along rivers—a region vast in scope and natural riches. This empire’s fi gureheads were the sons and daughters of Xin, but they were almost powerless. In practice, Thassilon was ruled by the seven powerful runelords, maniacal arcanists who used magic to fuel their own decadence. It’s unclear from records whether the same seven extended their lives over hundreds of years or their apprentices took their names and titles upon their masters’ deaths.



Thassilon consisted of seven individual domains, each of which was ruled by one of the seven runelords. Under distinct and exploitive law, each domain embodied its ruler’s favored virtues
of rule. Each runelord had a capitol city that shared the name of his domain, but was prefaced by the word “Xin”—ancient Thassilonian for “imperial” and “throne of,” after the fi rst emperor. Thus, the capitol of Shalast was called Xin-Shalast.


Why Thassilon fell remains a mystery, but as the end drew near, the seven wizard kings of Thassilon retreated into the depths of their greatest monuments, entombing themselves with orders for their minions to release them later to reclaim their empire. Alas, Thassilon’s minions defied their orders, were enslaved, or were slaughtered. With no one left to waken them, the wizard-kings of Thassilon slumbered for countless ages. The few scholars who research the ancient empire maintain three common theories for its collapse.

The Aboleth’s Revenge: One theory is that aboleths destroyed the empire in a long delayed retaliation for the runelords’ theft or corruption of aboleth glyph and lifecreation magic. The invasion is said to have come from the sea, driving inland along the rivers and lakes, and ultimately subverting and destroying anyone who professed allegiance to the rune lords. Evidence for this theory is sketchy at best, as most scholars are unwilling to consult primary sources among the aboleths.

Thassilon and Beyond: In time, the law and charity of the early empire gave way to corruption, cronyism, and the summoning of aberrations from beyond the planes. These included the shining children, the scarlet walkers, the inverted giants, and the Oliphaunt of Jandelay, a creature so powerful and yet so diffi cult to control that it was summoned only once to destroy an invading army—and even so, dismissing it afterwards destroyed a quarter of the Peacock Legion. This theory holds that the madness of these unknowable creatures warped all they touched, turning the rune magic of Thassilon into a mockery of its former glory. Without its magic, inherently corrupted Thassilon fell apart into squabbling fiefdoms, none potent enough to restore a central throne. Unfortunately, no one can prove a change in the quality of the empire’s magic, which is long since lost.

Revolt of the Giants: This theory holds that the rune giants who served the runelords and secured their power revolted against their masters one summer just before the harvest, setting fi elds and forests ablaze, tearing down monuments they had built, and devouring every soldier, every priest of Lissalaa, every monk of the Thassilonian Order, and every wizard and sorcerer they could find. They destroyed every sign of the Rune Goddess and the Peacock Spirit, and forbade anyone from learning or using the runes ever again. After destroying the ruling class, the rune giants wandered into the north, never to return. Some scholars claim this was a symptom of the empire’s fall, not its cause.
