The House of Horrors quest in Skyrim is located in the city of Markarth. For this quest, I am taking Stenvar to help me clean this mess.
Vigilant Tyranus asked me to help him search inside an abandoned house for his investigation. In The House of Horrors Quest, you will be introduced to Molag Bal, Lord of Domination.
Molag Bal wants you to complete one last task to prove yourself worthy. Your next quest is to find the Priest of Boethiah.
