Markath is a beautiful stone city, but also one of the strangest hold in Skyrim. Jarl Igmund is the ruler of the Reach This quest begins outside the Abandoned House in Markarth. Tyranus, a Vigilant of Stendarr, will ask the Dragonborn to help him search an abandoned house for evidence of daedric activity. I have completed house of horrors, and want to know if I can use the abandoned house to store things indefinitely.
It seems like a normal abandoned house, but a tunnel can be found in the basement that leads to the Altar of Molag Bal.
