"Mysteries of the Vestibule!"
Gilgamesh has been brainwashed by Ajak into believing that the Eternals have been replaced by Deviants, sending him into a murderous rampage. He has murdered Makkari, which triggered the Dreaming Celestial's death song for the planet. Worse, Gilgamesh has rushed to destroy the device that respawns fallen Eternals. Without Makkari, Earth is doomed. Only Sersi holds the key to their salvation.
