Contact with the humanoids in the previously discovered Backdoor (formally assigned Backdoor Serial Number [BSN] #945360, informally known as Skeld) has been successful. Each of them have been identified as wearing a protective suit, although attempts in removing them have been met with hostility and thus unsuccessful. Each of them seem to adorn their suits with different accessories, and they are differentiated mainly by color, referring to each other as such based on the color of their protective suits. They've also identified themselves as "crewmates", and seem to believe we are one of them, despite clear differences in our suits and our much larger stature.
Their dimension seems to be stuck in a timeloop of sorts. After a few visits, we've identified a pattern. Every loop, around 4 to 15 of them show up, and among them, there are hidden a small number of "impostors", who look identical to a normal crewmate but has to goal of eliminating all other lifeforms. Cremates have the duty to perform various tasks around the facility, and collect clues towards discovering who the impostor is, coming to an agreement in order to "vote" out a suspected impostor. So far, we have not observed what happens were the crewmates to be unsuccessful and the impostors be allowed to succeed, although due to orders given by the Team Leader to not interfere, the crewmates had wrongfully voted out two crewmates and one had been murdered, even after our team had correctly deduced the impostors.
