Quest: Path to Oakhaven

Boiler Room: After the intro cutscene, escape through the vent into the boiler room. Collect the note on the table and the poster collectible (Rosmark’s Gate and Bastion) on the wall. Exit the room by waiting for the guard outside the window to turn away, then leave through the door. Knock on the next door to speak with Aunt Mary, then climb the ladder.

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 the vent on the left.

Workshop: Observe the guards' patrol patterns from the vent. Wait for the guard near the metal grates to leave the room. Descend the stairs, carefully navigate around the metal grates, and proceed left towards the stairs. Look through the window to see the red crank controlling the wheel. Exit through the door into the engine room.

Steam Engine: Wait for a guard to walk onto the metal grate. Descend the stairs and hide behind the big wheel. Once the second guard passes, move to the area with the red crank wheel. Hide behind the middle wall and wait for the guard to pass through. Interact with the crank to turn on the machine, masking sound. Immediately sneak up the stairs to the upper grate area. Cross the grate while the wheel is on. Use moving boxes to cross to the right and reach the ladder without being seen by the guard across the way. This action contributes to the 'Escape Artist' achievement.

The Rooftops: After reaching the rooftops, continue left and climb the ledge. Proceed across the rooftops. Collect the note on the vent. Vault over the gate to the left of the note. Continue to the next rooftop and descend the ladders to the ground floor.

Repair Shop: 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 side of the dead end. Backtrack to where you climbed down from the rooftops. Near the birds on the steel roofs, make noise by walking near them to distract the guard. Vault over the gate to the left. Grab the note on the table behind the gate.

The Pub (Wine Storage): Enter the next open doorway. After the cutscene with the guard above, quickly run across the yard to the left (hold Shift and press M1). Wait for the second revolving guard's back to turn, then walk down the wooden walkway. Grab the note on the barrel near the vault gate. Climb over the gate to the left. Enter the vent to access the warehouse and collect a note and the 'Madame Cecilia' collectible.
