Last Song Pete's beacon allows the various rescue parties to converge on Ophelia's hideout. The Sword Roses and Cornwallises arrive first, greeting a tearful Pete before being confronted by Ophelia herself, who begins her endgame: the casting of a Grand Aria, a high-level ritual that creates a pocket universe of the caster's design. Entrapped within a world in the form of Ophelia's womb that will infinitely birth chimeras, the Sword Roses attack her to end the spell but are swiftly overcome. But Ophelia hesitates, reminded of her own loneliness amidst their companionship. At that moment, Whitrow and Godfrey arrive, and Whitrow uses their enchanted voice to break into her Grand Aria from outside, calming and embracing the dying Ophelia before they both vanish into light. The rescue parties and kidnap victims return to the surface and reunite with Katie, Guy, and Marco the troll, and Oliver wonders in his internal monologue about their possible futures as the Sword Roses pass by Professors Aldiss, Forghieri, Gilchrist, and Headmistress Esmeralda – before being jolted out of his thoughts by a hungry Nanao.
