Azlant

Azlant is a lost continent in the Arcadian Ocean that was the first center of human culture on Golarion. Brought together by the alien intelligence of the Aboleth, Azlanti society and culture grew by leaps and bounds until their arrogant leaders began to think of themselves as superior to their inhuman masters. In retribution, the Aboleth called down the Starstone], sinking the entire continent and condemning Golarion to the Age of Darkness. Now all that remains of the once-mighty continent are a string of islands and atolls spread across a large swath of the mid-Arcadian; they are the only parts of the continent still above sea level.

Geography
Earthfall shattered the continent of Azlant, sinking it to the bottom of the sea, where it was reduced to a maze of sea-canyons. The island of Mordant Spire, on the far western edge of Varisia, remains one of the few inhabited remnants of this once great continent. The elves who live there guard closely the secrets of old Azlant for fear that trespassers would bring a second doom upon the world.

What was once the Azlanti mainland begins roughly 1,000 miles west of the Arch of Aroden, and consists of a bewildering maze of cliffs, tors, and jagged channels sticking up out of the ocean. Many are honeycombed with ancient passages or topped with remnants of statues or buildings that beckon the curious. Most are quite inaccessible from sea level without the use of ropes and pulleys, and the ocean floor around them is littered with the wreckages of ships that were dashed against the sheer cliffs and shoals.

Because the magic-users of Azlant weaved their craft into the great civilization's buildings and other structures in order to increase durability and stability, a remarkable number of them have survived the intervening millennia.

History
Little is known of the history of the first human civilization other than the sad story of its destruction. Many scholars believe that the Azlanti arose from the slave pits of the Aboleth, possibly indicating that their masters had engineered the Azlanti from primitive human stock and gifted them with intelligence and power, though there is no known evidence to back this theory. Others claim that the Aboleth simply set the early nomadic and cave-dwelling humans on the path to an advanced culture. Whatever the case may be, the Azlanti culture flourished for thousands of years upon the large continent in the middle of the Arcadian Ocean, reaching heights of art, philosophy, and science previously undreamt of by humans.

War with Ydersius
Myths tell of an ancient war between the Azlanti and a race known as the Serpentfolk. The Azlanti are said to have driven their enemies off the face of Golarion and into the Darklands. In the war's final battle, Savith, an Azlanti hero, beheaded the serpent god Ydersius in the Darklands realm of Sekamina.

Founding of Thassilon
It is also rumored that exiles of Azlant founded the empire of Thassilon.

Zura
Some legends state that the demon lord Zura was once a queen of Azlant who lusted after eternal life. In these tales, Zura's depraved acts led to Azlant falling into decadence and was one of the catalysts for the Age of Darkness

Sun Temple Colony
The Chelish province of Andoran sent out a fleet of ships to build a colony upon one of the few remaining islands of Azlant. Over a dozen ships perished in the voyage over the treacherous Arcadian Ocean, and the rest wrecked upon the sharp reefs near the coast. When the 200 survivors landed, they thanked Abadar for having survived and climbed the nearest high hill. There they found an ancient temple dedicated to some forgotten Azlanti sun god. They founded their Sun Temple Colony there, and did their best to keep the settlement going over the following centuries. Contact between the colony and the homeland became more sporadic, until all communication ceased sometime. The final message was incomprehensible, stating something about a "weeping gate" and warning of "an inner eye in the minds of us all". Since then no one has heard from the colonists, although passing ships report still seeing strange lights coming from the island from time to time; the colony's ultimate fate remains a mystery

Culture
Ancient Azlant was the most magically and technologically advanced human culture that ever existed, and the few artifacts which surface in the markets around the Inner Sea from time to time still draw great wonder and praise. Azlanti architectural styles or symbols have been copied from ruins and have inspired countless cultures throughout the centuries.

Inhabitants
No pure-blooded Azlanti survive to the present, although their genetic influence is noticeable in today's Taldans and Chelaxians. The Azlanti were a proud race with skin tones ranging from olive to pale white and predominantly dark hair. High brows and receding hairlines, in addition to eyes of a deep purple color, are still seen as Azlanti characteristics, and held in high regard in Taldor and Cheliax. Taldans in particular claim that their empire was founded by descendants of Azlant, who displaced the local humans. The god Aroden is said to have been the last full-blooded Azlanti, and with his ascension, that bloodline seems to have come to a close.

As most of what remains of the continent is now located on the bottom of the Arcadian Ocean, the majority of its current inhabitants are water-breathing creatures such as aquatic elves, gillmen, and merfolk.
