Open the passage in the fireplace pt. 2 | Walkthrough Black Mirror Walkthrough
Last update: Friday, December 8, 2017
Go back to the hall and take a look at the big globe in the center. Look for the lock while in zoom. You have to use the key to the office again.
This time set the key as follows. The first part (1) is fixed and hence it is our point of reference. 2 goes 90 degrees right. 3 and 5 should be parallel to 1; 4 ought to go 90 degrees to the left. You can activate this lock before getting the final part of the key as well.
Turn the key so that you only see the "bottom" - this will let you see whether you've set it right.
After you unlock the globe, you can manipulate both hemispheres. In order to set the right configuration, use the information you got from the small globes - Australia (Tasmania) and Spain.
How to set the globe? Well, see above: the highlighter part is our point of reference. Spain is above it (you have to increase the height of the perspective to see it) and Tasmania is below (although it's obscured by the dark rim). You can see part of Australia above the rim.
First, move the camera as far up as you can to be able to see Europe. Spain should go directly above the marker. Then lower the camera to be able to see Tasmania - a small island south-east from Australia. Set the lower half of the glove so that Tasmania is directly below the marker.
If you do it the right way, you will get a tablet with runes - we need it to unlock the passage through the fireplace.
According to the tablet, Algiz rune (a tree) is first and the Gebo (a kind of an X, only skewed) is last. Unfortunately we don't know which is the middle one. However, David has seen that rune - remember the one you saw in the Castle's old wing (the Perhro rune). It's the one. If you press them in the right order, the passage will stand ajar. Go inside.
