House Ustav was the royal family which ruled Ustalav from its founding in the 24th century AR, until the coming of the Whispering Tyrant in 3203 AR. Descended from the country's founder, Soividia Ustav, this Varisian family was destroyed in the long, dark years of the Lich's rule. The monarchs of House Ustav ruled with absolute power over the squabbling Ustalavan noble houses of that country until 2862 AR, when Princess Carmina Ustav divided the country into 16 semi-autonomous counties, owing allegiance to the crown.
