Telflamm is usually considered to be the biggest and most important city in Thesk, however, Telflamm is actually an independent city-state but wields so much power and influence over the country that it might as well be the capital. Telflamm was officially founded in 926 DR by Windyn Balindre, who moved his base of operations from Impiltur to this newly-built settlement and declared himself ‘Merchant Prince’, a hereditary title.
Situated as the start the incredibly profitable Golden Way] trading route, Telflamm quickly became the biggest trading station in the region, with most trade concerning the produce of Kara-Tur which is widely in demand all over Faerûn.
Sometime in the early part of the fourteenth century DR, the most wealthy and influential merchants in the city set up a regulating body to check any excesses the prince may or may not make. This Merchant’s Council is viewed as the real power in the city by most outsiders. This is not actually the case, however. Once the merchants began squabbling with Thesk and becoming too worried about their own profits, things started to go downhill. In 1360 DR, the Tuigan Horde weakened the city’s security and four years later The Sharkjaw Pirates extorted massive amounts of gold from the council to not interfere with Telflamm’s trade. The local thieves guild, the Shadowmasters of Telflamm slew the pirates two years later in a single night.
