Iarna is a small town on the Marbleflow River in the Irriseni province of Wintercrux. The town is a popular destination for Jadwiga and rich foreign merchants because of its famous hot springs. There are three resorts catering to the aristocracy as well as expensive restaurants and two grand theaters.
The hot springs began bubbling up some 200 years ago and are thought to have magical and medicinal powers although nothing has been proven. Hundreds of ageing or sick Jadwiga bathe in the hot springs every year. The truth is that a trapped and insane magma elemental heats Iarna's springs. The elemental was summoned by druids of the Heralds of Summer's Return 200 years ago but was captured and bound by Iarna's baroness at the time. The current ruler of Iarna, Baroness Iracetta knows the truth but prefers not to damage the town's businesses. The ageing Iracetta is a strong advertiser of the springs' therapeutic qualities.
