Ondolemar is the head of the Justiciars in Skyrim, and is charged with advancing Thalmor interests in Skyrim's major city of Markarth, seeking to persecute all Talos worshippers within the city. He resides in Understone Keep, where he paces back and forth near the Jarl's throne under the escort of two Thalmor Soldiers. When the Stormcloaks attack Markarth, he is nowhere to be seen.
