"Wait, Tree wait."
*plays some notes via MPE7's head and the whole room lights up*
There isn't much around in the area that you're in. Scratch that, there's nothing in the area you're currently in. In fact, it's a miracle you're walking around and breathing as you are right now. This place is in dead space in the abyss surrounding the world tree, albeit located right on the twilight leading into dead space proper.
The only two locations of interest are the World Tree behind you, which seems impossibly far away with a fair amount of black nothingness between you and it, or the old door with the paper sign taped onto it which is kind of close by.
The sign still reads: "Welcome new hires!"
Though you can now make out an extra bit of smaller text that you couldn't see before: "Please enter and wait to be received!"
From outside, the door doesn't seem like it connects to anything, just a doorway in the void. However, going into it, you find that there's a whole room on the other side of the door. The space is about 37 square meters, yet still a bit too small for all the things shoved in this presumed reception room.
There are about twelve chairs made of what is presumably plastic and metal, shaped like all the other chairs that you would typically find in waiting rooms. The floor is covered in some old dusty fur carpet that probably hasn't been cleaned for a long long while, harshly contrasting with the peeling pink wallpaper that stretches across all four walls of the room.
Looking closer, it seems that the person that painted this room had zero cares about what they were painting over, meaning that there are pipes, heat control panels, electricity boxes, and some alien bugs that are covered in paint, left there and never touched again, drowned in a garish pink paint.
From the ceiling hangs a couple of ceiling lights, that while certainly futuristic looking, are falling apart. Some hang to the ceiling by a literal wire, others have most of their lightbulb equivalents extinguished a long time ago, and others are installed backwards, shining toward the ceiling instead of into the room. In any case, the room is well lit because of the above average number of lights hanging on the ceiling.
The center point of the whole room is a wooden semi-circle desk, probably the place where the receptionist is supposed to greet new arrivals, except that it's kinda empty. No one is sitting at the desk, there's just a computer, a couple of job application forms, and an empty revolving chair. On the desk is a tiny paper Back Soon! card.
Towards the back of the room is the door to the rest of the building, which has been painted over in the same lurid pink that fills the rest of the room's walls. Above the painted over door is an old security camera, which looks to be long deactivated.
"We a-appear to be at th-the base of a s-s-structure called the 'W-World Tree'."
