The Door to an UnIdentified World

The Door to an UnIdentified World (also known as TDtaUW) is a door like object that when near, personnel begin to feel drawn to the door by a force of some kind. The personnel will then try to enter the tiny opening of an door the size of an average child. This door allows little man-like creatures to get access in and out through the door. The size of these creatures are unknown since they can change their size within any moment.
These creatures are codenamed TDtaUW-1. If seen they will begin to attack and kill the personnel until unseen. If there are multiple personnel they will not attack or inflict some sort of harm. These creatures are weak against fire and excessive amounts of light. When killed spores will spread out of the body and then infect within its range. If touched by these spores, you are to seek immediate help from medical personnel from the foundation. If not helped your body will quickly grow deadly mold that will quickly kill you.
