Savathûn, the Witch Queen

"You have failed in furthering your own goals, poor thing. Not mine."

--Savathûn to Malkanth, IX.X.I: Apocrypha, Inquisition of the Damned

Savathûn, the Witch Queen (formerly Sathona) is the Hive God of Cunning and one of the three original Ascendant Hive, alongside Oryx, the Taken King and Xivu Arath, God of War. She serves as one of the main antagonists of Season of Arrivals as she attempts to block our weekly communications with the Pyramids, as well as being the primary antagonist of the upcoming expansion The Witch Queen. She is responsible for orchestrating the entirety of Forsaken and Season of the Outlaw, creating an elaborate trap that would begin with the death of Cayde-6 and end with the entirety of the Dreaming City being Taken and caught in an eternal, three-week time loop. She is also responsible for the Hive-related events of Shadowkeep, including the construction of the Scarlet Keep and the Pit of Heresy dungeon.

Trivia

 * Savathûn can considered one of the primary antagonists of Destiny 2, due to the fact that several key events were orchestrated by her, as well as her final plan to ascend beyond Light and Dark.
 * Despite this, as of Beyond Light she has yet to make a physical appearance in-game. This is explained in the lore, as Eris reveals that it is not Savathûn's way to engage in direct confrontations and she prefers to send out minions and envoys to carry out menial tasks. However, it is theorised that she will make her first appearance in either Year 4 or The Witch Queen.
 * The Witch Queen is an upcoming expansion set to be released sometime in 2021, and is expected to focus on Savathûn and her final masterplan. Due to the title's resemblance to The Taken King it is theorised that Savathûn will be both a story boss and a raid boss, though as of Beyond Light this is pure speculation.
 * The title music for Shadowkeep is in fact Savathûn's viral chant/song, hinting at her presence in the political machinations of the Hidden Swarm as well as setting the stage for her larger role in Season of Arrivals.
