I haven't written this up yet.
The name is not as difficult to pronounce as it looks: subdivide it as Voubs-tro-wizasta. The local language is Voub and the people who speak it are Voubs.
Voubstrowizasta is north-north-east of Megalopolis, between the provinces of Selitionornacticold and Jattny.
Voubstrowizasta borders on the wilderness. The provincial governor is a warrior, Jutry Zedort, whose elder brother is the head of the Zedort Family in Megalopolis.
