Treteia

Treteia was a large kingdom on the Frontier Expanse during the Third Age. It served as the greatest barrier against the advancing Ti'kasonian army in the Second Age and was subsequently ruined. Despite having become a dangerous wasteland, it still serves as a buffer zone between Ti'kason and the rest of the world.

History
What is known of Treteia is based on oral tradition and the few surviving historical documents. There are mentions of it from the Second Age but it is suspected to have been on the peak of its power before the Ti'kasonian invasion on the early Third Age.

Treteia was the first major kingdom in the way of the Ti'kasonian Empire when it began its invasion across the Great Continent. There might've been other small westerner or easterner nations between Treteia and Ti'kason, but if they did exist, they were quickly subjugated into the Ti'kasonian Empire and no record of them remains. Treteia was in near-perpetual state of war for nearly 600 years before the Ti'kasonians finally managed to destroy its capital, the city of Truanca.

The remnants of Treteia remained an easterner-occupied land until the second century of the Fourth Age. The retreat of the easterners saw the beginning of a new era for Treteia and the westerners began settling it anew, forming small communities among the ruins. This era was cut short when an infestation of shadow creatures swept across Treteia, killing all the settlers. The threat was ended in the ruins of Truanca by hallow Galian but left Treteia a shunned and desolate wasteland. Only recently have people once more overcome their fear and begun expeditions to uncover the ruined land's forgotten secrets.

Hellhammer
The fortress of Hellhammer is one of the best-preserved remnants of ancient Treteia. It was built by hallow Bristlepike in the Second Age. Its function is unknown although most scholars suspect its purpose was not only to defend Treteia from the west. It's currently held by the Vycelant who do not let any outsiders delve far in the keep.
