Teresten became a garrisoned settlement of Zelendra after the end of the Brimstone War. This settlement at the mouth of the Greencrest River , on Hatran Island, would help protect the western settlements. The city was so far from Highmoor though, that it received little interest. It became largely forgotten and had to fend for itself. The city experienced stagnant growth for the few hundred years. The city was so isolated that when Queen Maude’s War erupted in 320, news of the war did not arrive until 322. When the terms of the Peace of Longring were hammered out in 343, neither Zelendra nor Illeria showed any interest. Queen Maude declared the city independent, similar as had been done in the Halavant East.
In 378, the city received an influx of population, as Serrileans arrived asking for a contract to exploit the regions timber resources. Concessions were given, and Teresten not only received an influx from the arrival of workers and investors, but received monetary compensation. The city slowly grew, beyond the wall that had divided the city from the rest of the island of Hatran for the past 300 years.
In the year 483, the city’s fishing fleet was attacked in the Gulf of _____ by Havenite fishermen, stating that this was their territory. Small skirmishes ensued, and Teresti fisherman had to retreat.
Teresten joined the A.S.T.A. as the smallest member city, with 8,000 residents in 499 as a way to prevent further conflict.
