Savathûn, the Witch Queen

"Savathûn, mother morph of Sathona, we delight in your sharp mind. [...] We are pleased with your use of our larvae to create mighty knights and plentiful warriors. Taox’s retreat to the Hydrogen Fountain proves your superior strength. But you must know that reclaiming your home is not enough."

- Worm Gods

Savathûn, also known as the "Witch-Queen", formerly known as Sathona, is a Hive Wizard and sister to Xivu Arath and Oryx, the Taken King. Together with her two siblings, she was a progenitor of the contemporary Hive species and one of its chief gods, having made a pact with the Worms of Fundament. She is driven to understand the deepest secrets of the universe. After the Hive's conquest of the Harmony, Savathûn and her Hive left her siblings and ventured into a black hole, claiming that they needed to grow different from each other.

Origins
"I am Sathona, middle daughter of the dead king. I will take back my home and eat the mother jelly. I will raise my spawn on the corpse of the Helium King. On my right eye I promise this."

- Sathona

Savathun was born Sathona, on the planet Fundament. She was one of a short-lived species whose homeworld had crashed into Fundament millions of years earlier, with the shards of the planet forming Fundament's continents. The Osmium Court was one such continent, ruled by the Osmium King, and Sathona was his second-born daughter, older sister to Xi Ro and younger sister to Aurash. The three sisters were tutored by Taox, a sterile Mother, the proto-Hive morph capable of spawning children, which also allowed them to live longer by eating "Mother-jelly" at adulthood. The proto-Hive's harsh lives convinced Sathona at an early age to become a Mother, not because she wanted children or feared dying, but because she wanted to live long enough to have meaning in her life.

However, by the time her father turned ten Fundament years (a lifetime by the standards of their species), he had discovered a dead Worm on the shores of the Osmium Court, which he started tending to as a familiar, and began raving that the Syzygy, a prophesied disaster, would soon occur. While Aurash took her father's warnings to heart, Taox concluded that the King was falling to senility in his old age, and that none of his daughters, which were two years old at the time, could properly rule the Osmium Court and protect it from the Helium Court, a rival kingdom. While acknowledging that Sathona was a brilliant thinker, Taox noted that she could not fight. In desperation, Taox sent a message to the rulers of the Helium Court, the Helium Drinkers, saying that she would help them assassinate the King and his daughters if they installed her as their regent. The Helium Drinkers accepted Taox's proposal and attacked, killing the King but failing to kill his daughters. In the confusion, Sathona managed to steal her father's Worm in their escape. Reaching Aurash's ship, the three sisters made a blood oath to return and take vengeance, with Sathona vowing that she would become a Mother and raise her spawn on the corpses of the Helium Drinkers.

Over the next year, the three sisters sailed the oceans of Fundament. During this time, Sathona began to hear her father's worm speak to her, guiding her to acts that would save the sisters over the year. Finally, the three sisters found a ship they named "the needle", built of high technology, but whose crew had died obscenely after hatching an egg from a creature that they could not recognize. Xi Ro insisted that they sell the ship at the Kaharn Atoll, where the species of Fundament gathered, saying that an auction could raise them enough money to hire mercenaries to fight the Helium Drinkers. However, Sathona told Xi Ro that the ship was worthless. Aurash instead suggested that they repair the ship. With prompting from the Worm, Sathona agreed with Aurash and convinced Xi Ro to repair the ship.

Over the next two years, the sisters repaired the needle, but by this point, the sisters were five years old. Sathona raised her fears that she would soon be too old to eat mother-jelly, and that the sisters would be unable to fulfill their oath. Aurash said that the sisters had to dive beneath the oceans of Fundament, traveling to the planet's core. Xi Ro warned that this was how the crew had died, but Sathona, urged on by the Worm, agreed with Aurash. The sisters took the needle into the deep. They finally reached a point where they could use the ship's sensors on the oceans. To their horror, they discovered that the Syzygy was real, and that Fundament's moons had already aligned. Just then, they were encountered by the Leviathan, a creature long spoken of in proto-Hive myth. The Leviathan warned the sisters that they needed to turn back, or else would unleash disaster upon the universe, saying that they faced a choice between the Light, which offered civilization, and the Darkness, which offered only violence. However, the Leviathan offered no hope to the sisters to avoid the Syzygy. Sathona then revealed the Worm's help to her sisters, and how it urged them to go down. Rejecting the Leviathan's entreaties, the sisters dove into the core.

Reaching the very center of Fundament, the three sisters found the Worm Gods: Akka, Eir, Ur, Xol, and Yul. The Worm Gods offered the three sisters a chance for the proto-Hive to escape Fundament as well as achieve immortality. All they had to do was take the Worms larvae into them as symbiotes and spread them among the proto-Hive. The Worms posed the caveat that the sisters must never cease their natures: Xi Ro must always test her strength, Sathona must always be cunning, and Aurash must always try to understand. The sisters accepted the pact and became the first Hive: Xi Ro took the Knight morph and became Xivu Arath, Sathona took the Mother morph and became Savathûn, and Aurash took the King morph, transforming into a male and became Auryx, the King of the Hive.

Campaign of Destruction
"I don’t have a strict proof yet, you know. This thing we believe — that we’re liberating the universe by devouring it, that we’re cutting out the rot, that we’re on course to join the final shape — I haven’t found a strict, eternal proof. We might yet be wrong."

- Savathûn

As Auryx and his sisters forced an ultimatum on the remaining proto-Hive to accept the worms or perish, Auryx turned his attention to Fundament's moons, and the Ammonites there who had allied with the Traveler and gave asylum to Taox. Initially he was willing to negotiate with the Ammonites, but his sister Savathûn, under pressure from the Worms, killed Auryx as punishment. Rather than dying, Auryx's soul instead passed to his Ascendant realm, or throne world, where his soul resided until he returned to the mortal realm. Rebuked, Auryx purged what sympathy and goodwill he had left, becoming a merciless tyrant. He and his sisters warred with and killed one another on a regular basis after the defeat of the Ammonites, as part of their worship of the Sword-Logic and their attempt to become the sharpest blades in the universe, heading to their Ascendant realms when defeated. Their war of revenge against Taox had transformed into a campaign of genocide, when they slew the Ammonites and other interstellar civilizations to feed their worms. The lords of the Hive also established their Ascendant realms, with Auryx naming his the High War.

During the war with the Ecumene, Auryx came to realize that the Worm had deceived him and his sisters: their Worms appetites were growing past their ability to feed with death. Meeting with his sisters in his ascendant realm, surrounded by their servants (some of which despised them for showing weakness) they despaired over their dilemma. When his sisters offered their power to help Auryx find a way to save them, Auryx killed them, then used that power to confront his patron god Akka, the Worm of Secrets. He killed Akka so that he may steal its ability to call upon the Deep and created the Tablets of Ruin, which gave him the power to Take. His transformation complete, Auryx was now Oryx, the Taken King. During the subsequent war with the Ecumene, Oryx revived Xivu Arath in an act of war, and revived Savathûn in an act of cunning. He then decreed the tithe system: each Hive would kill their enemies, take some to feed their own worm, and tithe the rest to their superior. Thralls would tithe to Acolytes, Acolytes would tithe to Knights or Wizards, the Knights and Wizards would tithe to the Ascendant Hive, those who commanded legions of warriors and earned the right to enter the Hive gods' Ascendant realms. All of this violence would eventually reach Oryx, Savathûn, and Xivu Arath, allowing their worms to feed on violence while continuing to invoke their inner natures.

While Oryx was off studying the Deep, his son Crota was deceived by Savathûn into using his Cleaver to cut a portal in the High War, allowing the Vex to enter. For one hundred years the children of Oryx waged war with the Vex, which quickly deduced the Sword-Logic and worship of the Deep as key to attaining power in the High War. The situation become so severe that the Worm Eir Itself demanded that Oryx return and end the war. Quickly returning to the High War, Oryx used his powers to take the Vex and clear his throne world. Angered at his son's imperfection, Oryx threw Crota into the Vex gate network, decreeing that he return "victorious or die forgotten". Oryx recognized that the threat of the Vex invading his throne world could not happen again, so he moved the High War into a mighty Dreadnaught scrimshawed from the remains of Akka, stealing from Savathûn her Scalpel.

After Oryx confronted and captured Quria for the last time, he presented the Vex and its simulation to Savathûn as a gift. When she asked him what proof they had that what they were doing was right, Oryx simply replied that the Hive's existence was proof enough in their convictions to live eternal by the Sword-Logic. Following the war with the Harmony, Savathûn decided that her fleets would enter the black hole that the Harmony lived around, claiming that they would become stronger for it, while Xivu Arath took her fleets away from Oryx's as she felt he constrained her too much.
