Just like the Knight, Quirrel is an amnesiac and doesn't remember Hallownest, or his unknown association with Monomon the Dreamer, despite being a part of it in the past. His past is shrouded in mystery that is not made clear in the game. Quirrel is very enigmatic, though incredibly kindhearted, optimistic, and helpful to those he meets, including the Knight, who he guides. He has a calm and peaceful disposition, and although he wields a sharp nail and is an extremely skilled warrior and nail-wielder, he is pacifistic and only ever fights to protect himself and others (such as the Knight when he assists him). Quirrel wears Monomon's mask on his head for the majority of the game, but takes it off to undo the Teacher’s seal after helping the Knight defeat Uumuu. Shortly after this event, Quirrel remembers small parts of his past. Though he is still amnesic about his past and his association with the kingdom of Hallownest, he remains very much at peace, and very optimistic about his adventures, and admits that he is happy and astonished to witness the Knight’s prowess and to journey through Hallownest yet again. He mysteriously vanishes from Hallownest after his final appearance at the Blue Lake where all that remains is his nail. you are The Kinght. Takes place a few weeks after Quirrel's last appearance.

Mirage appears to be a robot with a blue chassis, with a singular emotive yellow eye that makes up the entirety of her face. She wears a black jacket over a white dress shirt, a diagonally striped red tie, and a similarly striped red miniskirt. The way Mirage dresses is disheveled, suggesting that she doesn't care much about her outward appearance.Mirage presents herself as confrontational and rude, being aggressive and quick to insult the player. Upon further dialogue her temper recedes, revealing her deeply nihilistic view of the world and herself. She reveals that her ill-mannered behavior is simply the result of her ever present existential dread.

Sebastian’s body is shaped similarly to that of a sea snake, in that it is elongated with blue scales. At the end of his body is a large tail fin. Sebastian’s skin is a light blue. His torso is humanoid, with two larger arms and one smaller arm on his left side. Sebastian’s hands are humanoid, although he only has four fingers with claw-like ends. Sebastian’s face retains a humanoid face (which is mostly always smiling) with fish-like features, such as an anglerfish bulb on his forehead, fin-like appendages on his head, sharp teeth, a fish-like mouth, and a third eye on his right side. He also has a gold/yellow ring on his pinkie finger (lower left arm). Sebastian runs a makeshift shop in which he sells items and supplies to prisoners in exchange for any research that they are carrying. He also supplies items to the player through Dead Drops, requesting kroner in exchange for items to be left at the Submarine Dock. Sebastian does not see convicts sent by Urbanshade as his enemies and is willing to help them in exchange for their help. The more times you exit and enter his shop, the more annoyed he gets, eventually kicking you out. Sebastian can also be seen while the player is viewing Documents, being the one who shows the documents to the player. He will often reply with snarky or comedic comments about each monster. Interestingly, Sebastian has been forbidden from showing Mr. Lopee's document. As of the Friendly Fire update, Sebastian is capable of harming/killing the player if one flashes him with a Flash Beacon. Upon using a Flash Beacon on Sebastian for the first time, he will grunt, and pickup said player before warning them "Don't do that again". Sebastian will then break the player's Flash Beacon before throwing them to the ground, dealing 50 DMG. if any player decides to flash him again, Sebastian will instead pull out a gun and shoot said player, instantly killing them.
