You'd been assigned, as a Class-D, to check up on the anomaly known as SCP 303. You'd been told it appears in closed doorways or windows, and creates a state of freezing dread and fear if its door is opened. As of right now, you're wandering almost aimlessly through the halls of the containment site used solely for 303. And then, whilst idly collecting items, you spot it.

In a doorway, staring at you. As much as it COULD stare, with a lack of eyes... Though, the fact it has a single, large mouth and nothing else on its face disturbs you. It just seems to stare, only its head visible through the window embedded in the door. Usually, it does nothing and you can move around it... But it seems to "stare" at you for a tad longer than it usually would.
