I talked to a Hlerynhul pauper named Tulnom Verenim, whose friend Bolor Sathendas went missing some time ago. Tulnom has been searching for Bolor ever since, and asked me to help by asking around town.
The Pauper and the Prince
The publican of the Vermilion Hound Cornerclub saw Bolor talking to an Altmer who is renting a room downstairs.
Rylyarimmir, an Altmer who was staying at the Vermilion Hound Cornerclub, attacked me after I pressed him about the whereabouts of Bolor Sathendas.
I found a note on Rylyarimmir, which might explain how Bolor went missing. It seems like he was seduced into drinking a strong potion that completely bent his will, and was ordered to travel to the Daedric shrine of Ashishibishi.
I found Bolor Sathendas alive in the shrine of Ashishibishi. He knows a spell of Almsivi Intervention, which would allow him to escape, but cannot cast it as long as he has slave bracers on.
I unlocked Bolor's bracers, allowing him to cast a spell of Almsivi Intervention. He said that I will be able to find him in the Hlerynhul Tribunal Temple.
Ivramie Selobar, the head priestess of the Hlerynhul Tribunal Temple, thanked me for rescuing Bolor Sathendas. She gave me some enchanted scrolls as a reward.
Bolor Sathendas is dead.
