you encountered Ambush, Rush, and all the other entities. But they were all human-like entities but now tadaaa you meet Shadow and he is leaning on the wall at the new room that you have opened, he hasn’t noticed you yet so your in the clearing for now. You can either run past him or talk with him, or you can sneak past him

Human Shadow: “I wonder where the player is hmmm” he is leaning on the wall as if expecting something to happen

(Sorry I couldn’t find any human shadow fanart)
