The Lady of the Mountain — Eriksholm: The Stolen Dream Walkthrough

Boiler Room: After the intro cutscene, escape through the vent into the boiler room. Collect the note on the table and the hanging poster collectible (Rosmark’s Gate and Bastion). Exit the room by waiting for a guard to turn away from the hallway, then proceed through the door and up the ladder after talking to Aunt Mary.

Attic: Upon entering the attic, two guards will appear. Hide behind boxes. Wait for one guard to investigate a noise, then sneak past him. Enter another vent on the left.

Workshop: Before exiting the vent, observe guard patrols. Exit the vent and move behind cover to the right. Wait for guards to move, then descend the stairs, avoiding metal grates. Look through the window to see the red crank controlling the wheel, then exit into the engine room.

Steam Engine: In the engine room, hide behind the big wheel as a guard patrols. Wait for the second guard to pass, then move to the red crank wheel area. Hide and wait for the guard to pass, then interact with the crank to turn on the machine, masking sound. Immediately ascend the stairs to the upper grate area. Cross the grate while the guard is distracted by the machine. Use moving boxes to reach the ladder on the right without being seen. This section is also where you can earn the 'Escape Artist' achievement.

The Rooftops: After reaching the rooftops, climb the ledge to the left. Be mindful of birds, which can alert guards but also serve as distractions. Continue across the rooftops, collect the note on the vent, and vault over the gate to the left. Descend ladders back to the ground floor.

Repair Shop: On the ground, walk right past the truck and down the stairs. Collect the 'Apple Gardens Travel Guide' collectible on the platform up the ladder on the left. Backtrack to where you climbed down from the rooftops. Use the birds on the steel roofs to distract the guard by making noise. Vault over the gate to the left. Collect the note on the table behind the gate.

The Pub: Enter the next open doorway. You'll see a cutscene of a patrolling guard. Quickly run across the yard to the left (hold Shift + M1). After passing the first revolving guard, wait for the second one's back to turn and walk down the wooden walkway. Collect the note on the barrel near the vault gate. Climb over the gate to the left. Inside the wine storage area, drop down or take the stairs and move toward the brick wall with a picture. Climb the ledge and enter the vent. Inside the vent, you can access the warehouse to collect a note and the 'Madame Cecilia' collectible. Exit the warehouse back to the wine storage deck. Use the birds on the roof to distract guards, then exit the area and circle around to the back right. Vault over the gate and proceed to the stairs. Collect the note on a crate at the bottom of the stairs. There are two paths forward, both containing collectibles.
