Aris Lantrosa: Arthas's companion among the Blood Sorcerers. She is killed during the assault but revived when Arthas gives her his blood.
Elendra Elutharis: Evenari survivor carried from Eilinor while dying from a blood-shadow sickness. Torrin removes the affliction, after which she appears far less connected to twilight.
Torrin: Rejoins two Crystallic fragments, survives opening the Tome of Stars, cures Elendra, and discovers how to lead the allied force through Venfallas one final time.
Vyr: Closes the Tome of Stars before it consumes Torrin and becomes its bearer, hearing a persistent static after the book takes an attunement.
Normandy Borthal: Fourth host of the Deathless Flame. He accepts Emrys's offer to ignite the allied army's weapons despite being warned about the flame's allure.
Emrys Valakar: Progenitor whose consciousness remains within the Deathless Flame. He tells Normandy that the flame's hosts are legion and grants him a single overwhelming use of its power.
Helena: Blood-bound prisoner of Acuras who escapes his presence, disables the machinery beneath Keph, and frees Demantrius.
Demantrius: Ancient Umtheran held within a sealed chamber connected to Keph's boiler system. Helena releases him at the episode's end.

Moon Lake Corruption: Blood spreads through the clear water like ink, transmitting sickness and mortality to Evenari throughout Venfallas.
Collapsing Twilight Veil: Failing natural and magical boundary that can carry the allied force once before breaking completely.

Keph Boiler Mechanism: Machinery beneath the keep that Helena disables before opening the chamber in which Demantrius is held.
Deathless Flame: Chartreuse soul-fire containing Emrys and earlier hosts. Its mass ignition grants the allied force a temporary answer to Acuras's deathless army.

Tome-Bound Static: High, distant noise that Vyr hears after accepting the Tome of Stars, indicating that the book has magically attached itself to her.
Twilight Passage: Torrin steps across the weakened boundary into Venfallas and later holds it open long enough for the entire allied force to cross.

Flame Communion: Normandy enters the soul forge within the Deathless Flame and speaks directly with Emrys and the memories of its former bearers.
