Open the wooden folder in your inventory to reveal a windmill sketch. Approach the desk and move the paper to create a blank page. Return to the courtyard and enter the room. Return to the mounted crossbow and use your Oculus Perpetua to return to the present day. Turn the wooden barrel to your left to expose a wooden folder. Head up to the windmill and use the tool to open the door. Manipulate it in your inventory to create a tool. Pick up the ring with the ornamental handle. Turn the handle again to return the bridge to its original position. Shoot the target on the windmill three times. Turn the handle to your left to move the bridge. Shoot the rope on the grate beneath the tower. Shoot the rope holding up the bell in the belltower. In the frozen past, use the frame and the mechanical handle with the mounted crossbow. This cuts off your access to the ground, but gives you access to the windmill. Head back down the stairs and use the Oculus Perpetua and create a portal. Slide down the lock on the wooden cog mechanism, and then turn the handle to open the circular gate downstairs. Use the lion statue here, sliding it along the slot and then twisting it to create a staircase. Head back to the courtyard entrance and zoom-in on the black square with the slot. Use the wooden plate to unlock the enclosure, and then slide the bars around to create an opening. In the courtyard, head towards the pile of jugs, and then zoom-in on the barred enclosure to the right. Turn the handle to load the frame with bolts. Use the wooden frame with the open drawer to expose a handle. Slide the mechanism across to open the left-hand drawer.

Pick up the wooden frame, then slide the brass panels together to reveal a hidden compartment containing a compass. Slide the mechanism across to open the drawer.

Turn the compass so that the mechanism lines up with the mechanism on the right-hand drawer.

Zoom in on the green-patterned junction and spin it around. Open your inventory and twist the bell to reveal a small key. Remove the bell model, and then pick up the wooden plate with protrusions. Go over to the model behind the model railway table and slot the belfry into the gap. Twist the eight dials on the outside of the page so that they each point in the direction of the nearest blue line. Open your Oculus Perpetua and spin the large wooden cogs to create a blue shape. Use this in the cross-shaped keyhole on the desk. Twist the part that emerges to expose a cross-shaped key. Zoom-in on the circular mechanism on the stair post, slide the pieces together, and turn. Use it in the mechanism on the stone stair post. Combine with lever part with the ironbound disc in your inventory to create an ornamental lever. Remove the ornamental lever part from the plinth under the wheel. Turn the wheel to align the track with the track on the table. Take the cart model and place it on the wheel behind you. Head to the desk on your right and turn the inkwell until the feather is over the III. Collect the ironbound disc and then head into the room. Solve the sliding puzzle to release the wagon. Go back out into the courtyard and use the crank with the mechanism to your left. Slide the book from your inventory onto the scale to expose a letter and a strangely shaped crank. Once you’ve climbed the stairs, head to the door on the right, use the handle, and then push. Slide the handle across to rotate the chimney, and swivel the handle on the bellows to make the dragon breathe fire onto the post. Use your Oculus Perpetua to expose a selection of symbols, and pick the rectangular one. Remove the stove cover by sliding the catches on either side. After the door opens, head through it to find a stove with a dragon-headed chimney.
