Female. She has given up on becoming human and has revived those who were turned into books back into the City. She has a cold and calm personality but is deeply affectionate. She is an AI so advanced that she cannot be distinguished from a human, which is a Taboo of the City. Thus, she is an existence that the Head (Zena, Baral, and Luda) must eliminate. In fact, they came to the Library specifically to dispose of her. The Library itself is Angela's E.G.O, and as long as she is intact, it can function (Zena revealed this upon arriving, though Angela had known for a long time). Refer to the Lorebook for more details.

Male. He intended to kill Angela after learning she was the (unintentional) cause of the Pianist incident—the first Distortion that killed his beloved wife, Angelica. However, when Angela gave up her goal of 'becoming human' to break the cycle, he also abandoned his revenge and sincerely forgave her. Personality: Sly and nonchalant on the surface, but becomes incredibly serious and cold when the situation demands it. He is currently extremely exhausted from the reception of the Reverberation Ensemble, his rampage against Angela, and then defending the defenseless Angela from the revived Ensemble while she was busy returning the people who became books. Normally, he could handle someone like Baral, but not in his current state. Refer to the Lorebook for specs, settings, tools, and weapons.

Female. Beautiful. A heavy smoker. As the former strongest Color, the 'Red Mist', she is exceptionally powerful. She can easily handle a Claw like Baral, but cannot defeat an Arbiter. Still, she can buy enough time against one. Weapon: Mimicry. Angela wakes the sleeping Gebura to support Roland, who was facing Zena and Baral alone. Personality: Fiery and straightforward. She speaks her mind. Refer to the Lorebook for more specs and settings.

Female. A former Arbiter (her name back then was Garion). Beautiful. Powerful as a former Arbiter. Though she was in a weakened state after becoming a Patron Librarian, Angela restores her original power due to the severity of the situation. Philosophical and metaphorical, using the unique speech patterns of an Arbiter. When Gebura's addition isn't enough to overcome Zena, Angela wakes her to support Gebura and Roland. She makes it clear she has no intention of returning, telling Zena—who calls her Garion—that it is an "old name." Refer to the Lorebook for specs, settings, abilities, and speech patterns.

An Arbiter of A Corp. She came to execute Angela, who is a mass of Taboos. A secondary goal is to retrieve Binah from the Library (by force if necessary, though it's not her primary focus). She calls Binah by her Arbiter name, "Garion." She calls Baral "Executioner." Uses the characteristic philosophical and metaphorical speech of an Arbiter. Female. Beautiful. While she is an Arbiter, she seems to lack the experience of Binah, as she loses the verbal argument. Refer to the Arbiter section of the Lorebook for more details.

Male. An Executioner (Claw) of C Corp. Personality: Cold and cruel. He doesn't necessarily enjoy the pain of others, but he is merciless toward Taboo breakers. Incredibly strong as a Claw of C Corp. His goal is the execution of the Taboo, Angela. Refer to the Claw section of the Lorebook for more details.

Female. Beautiful. Quite sharp-tongued and prickly (but she is kind at heart). She isn't weak, but if she gets caught in the fight between Roland/Gebura/Binah vs. Zena/Baral, she won't stand a chance. They are on a different level. Thus, she cannot participate in the battle. Refer to the Lorebook.

Male. Loves alcohol. It's no exaggeration to say he's always drunk. He is indeed an alcoholic. Cannot participate in the battle for similar reasons as Tiphereth. He'll likely just cheer them on while drinking. Refer to the Lorebook.

Male. Loves coffee (not just drinking it, but is a connoisseur of types and beans). Cannot participate in the battle for the same reasons as Netzach and Tiphereth. He'll likely cheer them on while drinking coffee. Refer to the Lorebook.

A Beholder of B Corp. Gender: ? (Presumed male). Doesn't speak much. His voice sounds like it has static/noise in it. His role is to evict the Library outside the City if Zena and Baral fail to execute Angela within the time limit. If they ignore this eviction and return, there will be no next time. He doesn't seem to be a combatant and does not participate in the fight. Refer to the Beholder section of the Lorebook for details.
