This western tower looks as though someone took a massive bat to the entranceway and let all their anger out. Metal is twisted, glass is crushed to powder, and anything that was once in one piece really isn't anymore. There might be a pattern to the breakage, perhaps, or something valuable in the wreckage, but it's difficult to see on a first scan through.

All further access past this initial room is prevented by a heavy metal door still in relatively good condition. To its left is a box a bit larger than two hands, still powered judging by the red-lit panel on it. It looks like it wants for some kind of key card or pass.

It is worth noting as well that the door is of significantly better and sturdier quality than the walls around it.

[A note: Groups A and B are both to begin with this issue, and further stage 1 headers will be provided once some solution is shaped.]
