It was one of the first Uyram cities, and achieved hegemony over the delta as early as 300. One of its earliest kings, Purtya, attempted to conquer the Ħomtso valley in 575; he was successfully resisted by a coalition led by Swiʔkyau, which burned Srethun to the ground and replaced it as regional overlord. The city was rebuilt, and came to once again eclipse Swiʔkyau under the rule of the empires of Tsopwan an then Uytai.
When Uykhrai, the capital of Uytai, was conquered by Krwŋ in 1457, the emperor Tyaisut moved to Srethun. The famous Festival House, one of the largest structures on Almea, was built here, to house the feasts which the emperor gave to the entire population of the capital, to show his generosity.
In the 3200s an internal coup put the Patriots (Ħwentai) in power, and they proceeded to turn Uytai into a dictatorship. Siad βo invaded in the 3350s, posing as liberators; they took over most of the country, but could not reduce Srethun. The Restoration (Turnon), based in the north, pushed down the Ħomtso valley; its leader Nonsaut captured Srethun in 3420, putting an end to the Patriots. The capital was moved from Twot to Srethun in 3435.
Srethun has a small Verdurian neighborhood; travelers heading north should be aware that it's the last place to get good Verdurian food and drink.
