Where is the room paper of Holographic Duff?

Where are the house drawings of the ancient scroll 5 in Holoduff? Take a boat from the port outside the helmet (the boat next to the captain who can take the task) to Raven Rock in Southam, and then walk out of the city along the door on the right. After rescuing the besieged guard captain from the farm, you can talk to him and receive the task of the dragon to investigate the temple of Milek, touch the body on the ground and get a note to receive the task of the imperial general to destroy the Frostmoth fortress. On the way to Frost Moth Castle, you will pass the house of Holoduff, and the entrance to the basement of the house is next to the box in the house.
