The Incident in the Rooms is a tragedy that happened deep in the Rooms surrounding Malice.
At 03:07 in room A-977, A-60 noticed that there was a "black goop" in the ceiling, which was also on the wall nearby. Seeing this, A-60 tasked A-250 in the next room to clean the mess. However, when A-250 attempted to wipe it off using its arm due to cleaning supplies being absent, the goop spread all over it. Abnormal behaviors were examined from it at 03:10, and it started acting aggressive towards other entities such as A-60, A-60', A-90, and A-90' because they were within the vicinity.
The goop spread even more, and two identical humanoid forms came out of the ever growing mess on the ceiling. One of them started fleeing the scene, while the other stayed behind to assist the spread of the goop.
As a result, A-60, A-60', A-90, and A-90' have been reported as missing in action and have not returned.
