Looking For Something?

You've reached a doorway. Perhaps this is the first time you have noticed it. Or maybe you are a regular visitor. Whichever, you know that this is not a normal door. This is not a door to keep you out. Nor is it to let you in, there are other ways to do that.
This door is a marker. A symbol indicating you are at an opening, that there is an inside and you are at the entrance. Though it is not the entrance itself and you cannot walk through this door, half an inclination is all that you need to easily and simply find the way in.
