The as capital of Imperial Galt, Isarn, swelled throughout the Age of Enthronement. As the ruling class became richer and the city grew more industrious, the rustic town of Halvon became l'endroit chic. For 200 years, from 4424 until the Revolution began, the small town of Halvon was built and rebuilt. Lavish manors in the high hillocks, and the crummy low-town there to serve the elite's every wish.
When bloody revolution began, the simple serving-folk of this quiet holiday town turned savage, and painted their old homes in the blood of their former masters. By the time the Grey Gardeners arrived to establish order, the lavish homes were completely overtaken and all the nobles dead.
Halvon today is often thought of as savage even among Galtans. The residents of the mansions-turned-tenements clash with one another for resources, but have participated under certain councils if they feel respected.
