Vlindrel Hall is a large home located in located up the stairs east of the Stonevault Repository in Markarth. The front door is protected by an advanced lock. A bill is posted next to the door.
There is a hiding spot in the southwest corner of the main room, in front of the entrance to the kitchen where Malaok works. Eoinpairn walks back and forth between helping out in the kitchen and heading over to the western corner of the dining table to make sure Deantenna doesn't need anything. Rowoakh and Desevaen are sat next to each other on the long northern side of the dining table. Barhurn and Ciana are chatting in front of the fireplace, to the east. Canaer works in the room north of the kitchen. An advanced safebox is sitting on a stone platform by the southern wall in Canaer's room.
Bevprugen wanders the northern hallway. He occasionally checks up on his drunk compatriots: Bedcallas is in the western room, and Ferrantia is in the eastern room. Walking in front of Ferrantia will not incur a bounty because she is incapacitated. Bedcallas can notice you, but his back is turned to his room's entrance, as he is constantly throwing up. The Luxurious Safebox (which is protected by a master lock) is located in Bedcallas's room. When you enter the room, take a left turn at the foot of the bed, and you'll find the safebox. It has 117 gold in it, and does not respawn.
