Alright, I can remember enough of the important details from the report's hard-copy to at least fill you guys in on some things.
Cyclops is among those missing, but you knew that. One guy came back from the expedition with no memory, and seemed like he was in a hurry when he came back through.
Footage analysis had a lot of static and distortion as is normal when dealing with the Slender Man, but cleared up enough occasionally to allow us to actually see what the cameras we built into the helmets were looking at. The Path was...disturbing. I'll leave it at that.
The team wandered around for a while, keeping each-other in line of sight, and eventually found a guy. Looked like a civilian or Irregular, and he was wounded. They didn't stay long, because good ol' Slender Man decided to show up and the team wisely made a run for it.
As soon as the footage cleared up, our sole returnee...returner? Whatever, he was the guy who came back when everyone else didn't, and I don't want to use the word 'survivor.' He was alone, and found a tree with something carved into it. He didn't get a good look at it, and consequently we didn't get a good look, because something freaked him out and he ran from that tree.
He found two other guys from the team again, and was trying to get back into contact with us at SMD HQ. One of the other two guys asked where Cyclops went, and the other one was confused as to who Cyclops was. This confirms the Path has an adverse effect on human minds.
Most other details are either unimportant, or didn't seem important, so I didn't bother committing the whole thing to memory. With my workload, there's only so much one guy can be expected to remember.
So, the Path expedition has been deemed...interesting by my superiors. With the recent disappearance of the after-action report, I decided to point out that this isn't exactly normal. PTC protocol has no such policies in place to deal with something supernatural completely deleting data from our computers, and the only other option is someone inside the organization deleting the report.
Central Command's treading lightly, now. They might start taking us a bit more seriously from now on.
