<A note was found on the floor of an elevator in welfare department the same day agents Oliver and Cedric disappeared>

The lights shut off not even a few minutes ago. Most of us kept calm, but the distinct screaming of clerks echoed in the hallways.
We were in the main room, and no orders were given to leave, but our oldest member, Cedric, he started staring at something beyond the door. It didn't take him long to break into a sprint. White damage did nothing to him, and he moved faster than I'd even seen him move before. I don't care if it was against protocol, I ran after him. I see now I never should have done that. He sprinted through a hallway, the left elevator, another hallway, and right before I could catch up, he slowed down and opened another door, and behind that door stood a giant black feathery figure holding a lantern, staring at Cedric with countless eyes. Cedric... he leaned in, reaching for the lantern, and the creature's eyes turned red, and, God, the crunch... I still hear it. Then, no chewing, just that horrid slurp as Cedric's... no, I don't want to think about. I ran as fast as I could, and now here I am, back in the elevator. None of the buttons seem to work, and I can hear the footsteps of that giant thing approaching. Please, if I don't make it out of here, take this to Mei over in training, she deserves to know that he's dead... and that she was right. I couldn't bear to, wait, I can see that lantern's light from under the elevator door. Oh no, I can hear breathing, that heavy, deep breathing, it's, OH GOD THE DOOR—

The rest of the note is covered by a bloodstain.
