Tom flattened out the crumpled piece of paper. He looked around, amid the darkness. The smell was horrible. He had no idea what he was even here for. He was told just to, "look". Whatever the hell that meant. What was he even looking for? What was this place? He began reading.
If you're reading this, chances are it's too late. Either this note was lying in a cave, or it was on my body.
How did this random letter know? And how was it 'too late'? He pressed on.
Either way, I'm dead. We're dead. Maybe I should fill you in, cause much like me, you were
probably blindfolded and told squat about this place.
"Damn right" Tom accidentally said aloud.
I'm Commander Leronov, call sign Leo, of Echo-18, and led the expedition of an anomalous object. I was told nothing about this anomaly until we got here, we were informed about SCP-XXXX. It's a seperate dimension, and looks the exact same as our own, only something lives here. And if I were you, I'd get out of here.
Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept surrounded by an electric chain link fence with barb wire at the top, no less than 3 m high. SCP-XXXX is to be guarded by 4 personnel at all times. SCP-XXXX is sealed with a 15 cm steel door, with an automatic release and open mechanism. Any attempts to research SCP-XXXX must be approved by a 3/4 vote from 05 Command.
Description: SCP-XXXX is a standard, wooden door made of pine, located at 3█.█████° N, 7█.█████° W, approx. 2█ miles from Site-██. SCP-XXXX appears to be a normal door, despite for the fact it leads to another dimension. SCP-XXXX requires a key to open, which will always be found under a pile of leaves approx. 3█ m away from the door. No correlation to the direction of the key has been found, and picks a random direction to manifest from.
When SCP-XXXX is unlocked, all people in a 20 m radius, or within direct eye contact of the door, will feel the impulse to go into it. Going through the door does not bring any anomalous to attention immediately and the landscape does not change. It is noted that any animals will not be effected by this phenomenon, and can walk through the door without travelling to the other dimension.
