After 2 hours of looking through every last corridor and slaughtering innocent and upstanding royal guards..
I decided to use the [ ] cheat.. so I appear in a room next to the painting..
Then I proceed to legitimatly look for the exit.. but seriously, I am 99.999% sure there is NO WAY back out from the location of the painting.. the area seems to be a completely seperate tomb within the bowels of wayrest with no path leading back to the main area.
so I had to use alt + f11
How in the hell did people manage this back in the day? I literally did a complete wall to wall/corner to corner check and there seems no coherant path back to the main castle, the place I spent the first 2 hours searching. ridiculous.
Maybe it was an invisible wall door? likely answer.
Oh a question..
What is the significance of those unopenable doors with the brick wall texture?
