Enter the Revenant

(From the Point of view of the lead rober after the event)

I had felt something was off before the hit, like something was watching us. I am sure the others felt it as well but didn't voice it. When I crouched down in front of the door to pick it, the feeling vanished. I blamed it on my imagination and got back to working on the lock. It took me a second to get it open, but as we stepped through the door the sensation returned. stronger. when the last of us entered the house I shut the door behind us and looked around, it was a hall with a two doors to each side and opened up to a common area and a set of stairs to the second floor. Three people decided to head up the stairs, I stayed in the commons and the other two checked the doors in the hall. The unsettling feeling grew stronger and stronger, until I heard a scream and thump coming from one of the doors in the hall. We all ran to the door as fast as possible, expecting to see our friend on the floor but when we stepped in, the room was empty. It was some kind of office, rather bare but still identifiable there was a window behind a desk and chair. The window was open and the torn curtains were fluttering in the wind, and a the light that poured in through the open window showed a small puddle on the floor in the middle of the desk. I crouched down and picked my finger into it, it was viscous and warm with a pungent scent. It was blood. The quantity suggested that the injury that produced the blood was nonlethal. I proceeded to the window and saw that something had been pulled through it, scratching the windowsill in the process I peaked my head out the window and caught sight of it, it was humanoid with smooth gray skin that had texture and broke at the joints by a black material that reflected no light, the smooth shell contoured and flowed like it was natural similar to the chitin of bugs. Its head was smooth and featureless except a pair of cold pale lights which were what I assumed was its eyes. I quickly yanked my head into the house and slammed the window shut and locked it,  before turning to the rest of the team and said, "We need to quickly lock all of the windows in the house, there is something out there", they reacted instantly and ran through the house, raising hell in their paths, after we locked the windows we gathered in the commons I drew a bow from my back and pulled out and notched a bodkin arrow as the others drew their weapons, focusing on the doors and stairs. I hear a slight noise above us and glance up to see those pale white lights, "Above" I shout and dive to the towards the entrance before turning to draw the bow and aim it the thing. It had landed on one of my teammates and knocked him to the ground, someone swung a sword at it to only see it bounce off of its skin. The monster turned and gripped the mans forearm before tightening its grip. I saw an opportunity to strike and realesed the arrow towards its back only for it to bounce off and lodge into my freind's leg. The other uninjured rober and I ran down the hall and towards the door he was slightly behind me and we were half way down the hall when a bright light shined behind me. I peaked over my shoulder to see what happened, the robber behind me had fell to the ground with smoke rising from him, magic. I quickly found a door that goes opposite to the office and quickly open it before closing it behind me and barred it with a broom. I had locked myself into a cellar, great.
