In Levianta, a mysterious voice, the "HER whisper", speaks as Elluka Chirclatia, instructing her fiancé Kiril to put her corpse in the Sin ark at the temple in order to revive her. The whisper goes on to explain how the country is declining due to the desires of others, and needs to be reset by the two of them; stating that Kiril has the "miracle" in his hands and urges him inside the temple. Another whisper, "her whisper," comments on Kiril's actions with puzzlement. Following this, an unidentified whisper then begins to urge Kiril to finish his task with increasing urgency.
Suddenly, a "miracle" occurs due to the Sin; the wildlife and populace of Levianta become engulfed in an explosion. Later, a "Lu li la" melody is heard, and Elluka is brought back to life, gaining immortality in the process, only to see everything and everyone gone. At the same time, two faint lights fall towards Held's Forest.
