Since this building is older there is a fire escape but its old and covered in rust. Still its the best chance you have. You start scarmbling down and since you have to turn around to go down you get a good look at the battle. the two creatures are tearing each other apart. Black blood covers the ground but it looks like the new creature is winning. It moves incredibly fast and almost seems to use the darkness itself as a weapon and a defense. The fight quickly moves out of view as you continue to climb down the fire escape ladder. Your down two stories now when the worst thing you could hear reaches your ears... its the screech of the bolts pulling out of the old concrete.
