Selendra Cassiandros: Marquis of Gavra who uses a Crystallic fragment to reactivate the city's glint towers. The effort burns her hands and rapidly consumes her life until the Harbingers remove the artifact and carry her toward the harbor.
Torrin: Sees broken Veyan civilization within the advancing storm, removes the Crystallic from Cassiandros, and remembers a Veyan lesson about power, light, and sacrifice.
Helena: Uses the legend of Tyve to awaken the Crystallic twice. Her final ignition restores Gavra's defenses and releases two citizens from the darkness possessing them.
Bjorn: Carries Cassiandros during the escape and is privately confronted by Mathias, who tests his understanding of selfishness, sacrifice, and responsibility.
Mathias Ephelthine: Uses Torrin's communion with the Crystallic to speak with Bjorn. He says Normandy must enter the Ithelion and offers prosperity for Bjorn's people in exchange for cooperation.

Zandra: Fading divine traveler who admits that she is frightened and says Cassiandros's fate is not hers to decide. She remains protected by Lendo and Ned during the flight to the harbor.
Whisper: Searches unsuccessfully for Graham, follows the others to the wharf, and boards the Maelstrodomus during the fight for the ship.
Ithelion: Lost source of Piln's radiance. Its absence leaves Gavra's glint towers powerless unless the Crystallic supplies another compatible light.

Harbinger of Light Prophecy: Helena's understanding of light, hope, and the legend of Tyve allows her to awaken the Crystallic against the approaching darkness.

Velpa Trading Company: Commercial house whose leader and armed militia claim the Maelstrodomus and fight the Harbingers for control of it.

The Vey: Torrin's forgotten people, whose ruined civilization appears within the storm and whose teachings are carried by the Crystallic.

Veyan Echoes: Figures and structures from Torrin's lost civilization that appear within the storm and later move through the city as hostile shadows.

Flooded Streets: Torrential rain transforms Gavra's roads into violent channels while the approaching wall shakes the castle and harbor.
Crystallic Fragment: Artifact carried by Cassiandros and capable of powering Gavra's glint network. It responds to self-giving light but burns those who sustain it.
Maelstrodomus: Enormous Velpan prototype of wood and iron, believed to be the only available vessel capable of surviving the Maligned Maelstrom and reaching Tyve's mainland.
Glint Towers: Gavra's defensive light network, normally sustained by Piln. Cassiandros, Torrin, and Helena use the Crystallic to ignite it temporarily.
Stefon's Vial: Helena's empty vessel, held beside the Crystallic while she invokes the Ithelion and the ancient legend of Tyve.
Marquis's Brooch: Mark of Cassiandros's authority carried by the group as they approach Wylas and the contested ship.
Crystallic Attunement: Direct contact allows Cassiandros, Torrin, and Helena to release the fragment's light, but the power can overwhelm the body or pull the bearer into visions.
Veyan Lesson of Power: Torrin remembers being taught that true power is given rather than taken and that the Crystallic reflects the light within its bearer.
Mathias's Communion: Mathias diverts Bjorn into a private mental space through the Crystallic and attempts to secure his cooperation through promises and questions about sacrifice.

Cassiandros's Last Defense: The Marquis chooses to burn away her life through the Crystallic so Gavra's people have additional time before the darkness arrives.
Torrin's Childhood Teaching: A Veyan father figure tells the young Torrin that power comes through giving oneself and that inner light can awaken the Crystallic.
