|“||Mother! What's happening outside? The people! The fires!||”|
–Calliope, moments before death.
Calliope was the beloved daughter of Kratos and Lysandra. She, along with her mother, were unknowingly killed by Kratos as part of Ares' plot to harden Kratos' heart and make him a more powerful warrior in the process.
|“||You will die... and Calliope will live!||”|
–Kratos, fighting the Hades Phoenix.
Calliope was born and raised in Sparta, living with her mother, Lysandra, in the country. At birth, it was revealed that Calliope suffered from a skin disease set out by Ares, which deemed her weak on in the eyes of Spartan Law and sentenced her to be sacrificed. She was only saved from her fate when Kratos set out on a quest for Ambrosia, after he consulted a healer who gave him The Fire of Apollo. The healer was hinted to be a disguised Zeus, Calliope's grandfather.
By the time Kratos returned to Sparta, he narrowly saved Calliope from being thrown to her death. Though the King of Sparta insisted that the law be upheld, Lysandra pleaded for Calliope's life and reasoned that if they could prove that a sip of Ambrosia could save a life, then he would have the final sip. Convinced, the King upheld his promise to Kratos, who then used the Ambrosia and cured Calliope.
While Calliope was easily frightened by her father's violent nature, in truth, Calliope, along with her mother, were the only people that did not fear him. She was quite close to her father, always anxiously awaiting Kratos' return from his campaigns to protect Sparta. On one such occasion, Kratos spent enough time with his daughter that he was able to carve a flute for her to play. As Calliope reached adolescence, she became an extremely talented flute player and composed many lilting and emotional melodies.
That was a standard wooden flute. Kratos carved it for Calliope in the past, in one of the times that he stayed long enough to see her between wars. In God of War: Chains of Olympus, Kratos was often "haunted" by a strange flute melody. Eventually, he recognized it as the melody from the flute of Calliope.
Both Calliope and Lysandra were in a village of worshippers for Athena when Kratos and a battalion of his soldiers arrived. Having since declared his allegiance to Ares, Kratos ordered his men to destroy the village and leave no survivors. Kratos decided to personally enter the Temple of Athena, brutally slain all within with his Blades of Chaos. Kratos' blood frenzy made him blind to whom he killed, until it was too late; Calliope and Lysandra, who were brought to the temple by Ares, were killed by him. It was revealed that it was Ares' manipulation to make Kratos the ultimate warrior that led to their deaths, since he thought that Kratos' family had held him back. Ever since the massacre, Kratos endured immense depression and guilt and continually sought forgiveness and freedom from his nightmares for his actions on that day.
After her death, Calliope, instead of being condemned to be among the rest of the departed souls of the Underworld, was allowed to live among the pure souls of the Elysium Fields, at the base of the Pillar of the World. Calliope lived well among the lush and peaceful surroundings, and was even allowed to wander beyond Elysium's boundaries, throughout the nearby Temple of Persephone, and took to playing her flute on the dock to the River Styx.
When Helios, the God of the Sun, was torn from the sky by Atlas, his Fire Steeds drove the Sun into the Earth, which plunged the entire world into darkness. Without Helios, Morpheus was unopposed, sought to seize permanent power, extended his black grip over the land, and enveloped all in darkness. The power of Morpheus affected even Kratos, as he became haunted by a strange lingering melody. Kratos could sense that it was familiar, and eventually realized that it was Calliope's song, having been allowed to come through the black fog of Morpheus all the way from the Underworld.
Kratos continued to hear the music on his quest to liberate Helios from Atlas' grip. His journey eventually took him into the Underworld, and, eventually to the Temple of Persephone. Kratos spotted Calliope on the temple docks, playing her flute. He called out to her, but Calliope merely turned around and re-entered the Temple. Kratos desperately followed his daughter throughout the temple, and eventually found Elysium's divine gates. Kratos consulted with Persephone, and, at that time, resolved to simply abandon mankind and the Gods to their fate at Morpheus' hands so that he could spend the rest of his days in peace with his daughter. After he gave up all of his magical abilities and weapons, and, in turn, his sins, Kratos became worthy of Elysium and was allowed to enter.
Upon arrival, Kratos and Calliope were happily reunited. The reunion was cut short, however, as Persephone revealed the scope of her plans to use Atlas to destroy the Pillar of the World, which would destroy both Earth and Mount Olympus, and kill all life. When Kratos realized that Elysium would fall too and that Calliope would die again, he charged at the Goddess, and stated that he would not lose his child again. However, he was easily knocked him away as Calliope ran to his side. Kratos knew that in order to stop Persephone's plan, he would be forced to make the impossibly painful decision to forever forsake his place with her and reluctantly pushed his daughter aside. Calliope was helpless to watch as her father massacred all the other souls in Elysium; he regained all of his abilities in the process, and became the Ghost of Sparta once again. Calliope broke down at the sight of a reborn Kratos as he departed to face and defeat both Atlas and Persephone.
After Kratos ended Persephone's life and bound Atlas to a fate of having to carry the Earth upon his shoulders forever, a depressed Calliope was seen, having lost the will to play the flute which her father gave her.
Images of both Calliope and Lysandra were created in a twisted illusion by Ares, during his final battle with Kratos, in an attempt to break Kratos' spirit by forcing him to witness their deaths once more. Kratos, however, was determined not to let them die again, and, beating the odds, defeated and killed an army of his Doppelgängers, and saved his family in the process. Ares, however, responded to his victory by re-taking control of the Blades of Chaos that he had bestowed on Kratos years ago, and commanded them to impale Calliope and Lysandra, which slain them both. While distraught, Kratos broke through the illusion and avenged both himself and his family upon Ares by killing him and took his throne as God of War.
In God of War III, during Zeus' battle with Kratos, the God-King sent Kratos plummeting into his own Psyche. As a result, Kratos was again forced to relive his own fears and nightmares. Under the guidance of Pandora, Kratos eventually encountered Lysandra, and Calliope. Finally freed from his own torment, Kratos hugged his family and allowed both himself and his family to forgive him for his actions. Kratos then broke free of Zeus' hold, and killed him.
A note left by Calliope was also found near The Three Judges, which read:
"The fires! The people screaming! I was so scared. Why didn't Father protect us? The Judges say I have to go now to Elysium and that it will be nice there. I miss my family."
- Calliope appeared at Kratos' death in Bit of War.
- Since Kratos was a Demigod, and Lysandra was Mortal, Calliope was 1/4 God, and 3/4 Human.
- Calliope would have been an adult when Kratos started his revenge on the Olympians. Since Calliope was approximately 8 when she died, she was killed six months before Kratos started to serve the Gods, plus 10 years of servitude to Zeus and the Gods of Olympus and 12.6 years of Kratos being the God of War. That meant thay Calliope was (chronologically) 31 by the end of God of War III.
- Calliope appeared in the Super Bowl Trailer for God of War: Ascension, 'From Ashes'.
- It was unknown if Calliope returned to life when the Gods were defeated. It also unknown if the souls of Elysium were able to come back like the ones in the Underworld were able to.
