How does Karnak's character interact with the choir?

Karnak's character is portrayed as a magical being, specifically as a sort of mystical figure with the ability to affect the narrative and the fate of the other characters who are part of the choir. This mystical quality allows Karnak to guide, influence, and sometimes challenge the choir members as they navigate their experiences and emotions throughout the story. Unlike a judge or a spectator, Karnak is not removed from the events but is integrally involved; their presence often signifies deeper themes of fate, choice, and the supernatural elements at play in the characters' lives. While the choir represents a collective human experience with their own unique voices and stories, Karnak serves as a bridge between the earthly plane and a more mystical realm, enhancing the emotional resonance of the choir’s journey. The choice of “as a fellow vocalist” does not align, as Karnak does not actively participate as an equal among the choir members but rather as a guiding force.
