Strange Door

Old news. Theres another one in that same area.

This was discussed to death in the elite mission thread (before Gaile posted that it doesn't exist). It's pretty clearly just decoration.

If you adjust your camera angle to look behind it you can see theres nothing but a mountain. Had this have been something special that they planned on adding in the near future there would have been some sort of pathway behind it to make it a bit more suspicious. It's possible that a "SF" type expansion could be made out of it if they adjusted the landscape. There are plenty of areas from the other two chapters that look as if they could be added to as well. One area in my head is one part of Underworld where there is light shining through the middle crack of this large door. two places in tyria I always thought would get expanded on are Grenths shrine in Dreadnaughts or even Balth's shrine in The falls.
