Savathûn, the Witch Queen

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. Her current whereabouts are unknown.

Biography
Savathun was born Sathona, on the planet Fundament. She was one of the Krill, 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 Krill morph capable of spawning children, which also allowed them to live longer by eating "Mother-jelly" at adulthood. The Kril'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, when her father turned ten Fundament years (a lifetime by Krill standards) he 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 Krill 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 Krill 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 Krill. 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.
