Serene is a woman who is selected to be trained in the Skill by Galen. Although Galen is particularly tough against her, she does eventually graduate from his training and becomes a member of Galen's Coterie.

After Galen's death and August's loss of the skill, Serene becomes the leader of the Coterie. She also inhabits the Skillmaster's quarters, setting it up as some sort of shrine to Galen.
