Zandra: The name Cecil uses in Tyve. Once the goddess of fate, she surrendered divinity and warns that accepting the beliefs of followers again would cause her to lose herself.
Horatio Vinvestler: The archwizard held within the Arcanium. Mathias abducts him after overwhelming his apprentices.
Mathias Ephelthine: An ancient wizard recently freed from the Chained City. He defeats Ariandre, Felsis, and Slip, then takes Horatio for an unknown purpose.
Ariandre, Felsis, and Slip: Horatio's surviving associates. Silence protects them from Mathias, and the Harbingers heal them after the attack.
Silence: An Argylus aligned with the Crystalline Order who guards the prisoners beneath the Arcanium. She saves Horatio's associates and offers to seal the Harbingers' scepter within a prison shard.
Ephastasia: An ancient and independent Blood Sorcerer devoted to Belgor'Vrack. She explains how collective belief can form a power capable of opposing the Chain.
Acuras: The former ruler of Keph, now trapped within Vyr's necklace. Ephastasia offers to resurrect him, but the Harbingers refuse because of his enslavement and slaughter of Keph's people.
Ilk: The keeper of the Twilight Temple. He delivers Cellus's warning that the Harbingers must divide and pursue several urgent paths before those opportunities close.
Bjork: Bjorn's son. After clashing with Torin and his father over the gods and the future of the clans, he accepts Skjold's Helm and prepares to travel with Helena.
Danimal: The Harbingers' ally at the Arcanium. He continues planning an aqueduct before returning to Keph with the group.

Cellus: A divine power who warns the Harbingers through Ilk and blesses Whisper's crossbow.
Belgor'Vrack: The Blood God served by Ephastasia.
The Chain: Draxus Kael's army of controlled soldiers. Roughly three hundred troops are force-marching toward Keph and are expected to arrive the following day.
The Crystalline Order: The order with which Silence claims shared purpose. Both seek to erase or imprison powers connected to the ending of worlds.
Blood Sorcerers: Practitioners who draw magical power from blood and souls. Nixon, Arthas, Aeris, and Ephastasia consider Acuras the most direct defense against the Chain.
Knights of Ithelias: Gavron's surviving knights at Keph. They prepare trenches, oil, barricades, and the gathered civilians for the coming siege.
The Barbarian Clans: The scattered peoples of Tyve whom Ilk says must be reunited. Helena and Bjork accept the first journey toward that alliance.
The Tear: A damaged portal network used by the Harbingers. Its first attempt to reach the Arcanium nearly destroys a test rope, but the second opens safely.
Silence's Shards: Mirror-like prisons beneath the Arcanium. Silence offers to use one to contain the Harbingers' dangerous scepter.
Whisper's Crossbow: A weapon blessed by Cellus. Ilk confirms its divine origin, making it the Harbingers' best hope of killing the Tangled One.
Skjold's Helm: The symbol carried by Bjorn. He gives it to Bjork after redefining Skjold as a shared ideal rather than a single ruler.
Collective Belief: Ephastasia explains that a belief shared by many people can become real power capable of resisting the Chain.
Dios Ostium: The sealed passage at the heart of the Harbingers' larger mission. Sethis claims she can open a dark route around it for a limited time.
The Arcanium: Horatio's tower and the prison guarded by Silence. Mathias devastates its upper chambers and abducts Horatio.
Skjold: Once the identity of a single ruler, Skjold is redefined by Bjorn as a shared ideal of freedom, justice, and self-determination.
