Vorhovis was of Barrayar's Vor class who served the Barrayaran Imperium as an Imperial Auditor. His specialty was foreign affairs and the activities of Galactics, and he was regarded by Gregor and Miles Vorkosigan as the top man among the auditors. Miles originally had hoped to have Vorhovis take on the investigation of ImpSec, and during his own investigation occasionally wished he could consult with Vorhovis to learn more about how to go about the task.
