Thassilon

Thassilon was an ancient, magically advanced human empire that dominated eastern Avistan for thousands of years. Its vast territory stretched from the northern reaches of the Crown of the World to the shores of the Inner Sea. The empire was founded by the Archons, powerful wizards who ruled with absolute authority, each specializing in one of the seven schools of magic: Enchantment, Evocation, Illusion, Abjuration, Necromancy, Transmutation, and Conjuration. These seven sins, as they are often referred to by later scholars, were the pillars of Thassilonian society and its downfall.

The Thassilonians were renowned for their colossal architecture, magically crafted artifacts, and extensive knowledge of arcane arts. Their cities were wonders of the ancient world, built with enchanted stone and powered by magical energies. However, the empire's insatiable ambition and the unchecked power of its Archons led to internal strife and a constant lust for more power. Each Archon sought to expand their influence and magical domain, often at the expense of others and the empire as a whole.

This internal conflict, coupled with over-reliance on magic and perhaps a catastrophic magical experiment, ultimately led to Thassilon's abrupt and violent collapse. The empire shattered, leaving behind scattered ruins, powerful magical relics, and a lingering legacy of arcane knowledge and cautionary tales. Remnants of Thassilonian civilization can still be found throughout its former territories, guarded by ancient magical wards and dangerous creatures.
