Aaronev Wilhelm Sturmvoraus, sixth Prince of Sturmhalten of that name and ruler of the town of Balan's Gap , is a major Spark, a Knight of Jove, and devoted to Lucrezia Mongfish. He is the father of two children; Lady Anevka; and Master Tarvek, who is also his heir. His unnamed wife, a direct descendant of the original Storm King, is evidently long deceased by the time the story starts.
