Final Update: The Rat Humanoid does not seem to be hostile. I see no need to impede anyone from interacting with it - though I strongly suggest you do not do so alone.
2nd Update: Wade Wilson took it upon himself to go into the basement and engage with the creature - prior to my securing of the stairwell. He is reporting that it is humanoid.
While exploring the basement, Mr. Parker and Mr. Stark reportedly stumbled across a large, rat-like creature. Tony sustained a concussion, but the animal did not directly attack.
Earlier Reports: 1st Update: There is a large, possibly dangerous creature in the basement The entrance to the basement is currently being guarded. There may be people still in the basement. If so, we'll need to get them out and lock the door. Please no one try to go down on their own. For both our own safety, and the creature's we need to formulate a plan, and equip a team to make first contact with it.
Original Report There's an active threat in the House. A large, hostile creature in the basement. It has injured Tony. I've secured the basement door. We will need to set up a watch rotation. Both the keep the creature down there until we figure out a plan, and to stop any of our younger residents from wandering down there.
