Does Sylvanas Die in Shadowlands 9.1?
At the end of the Sylvanas encounter in Sanctum of Domination, Sylvanas Windrunner does not die.
Similar to the Jaina Proudmoore fight back in Battle for Azeroth's Battle for Dazar'alor, a fight with a major lore character does not result in their death. Sylvanas's fate during the Mythic encounter has yet to be seen, as Mythic difficulty for Sanctum of Domination releases July 13.
Mythic difficulty will typically add another major part of the encounter, as well as increasing the amount of general mechanics there are in any given fight.
Back in Legion, the Mythic Gul'Dan encounter in Nighthold had a secret Illidan portion of the fight after Gul'dan was slain, we may see something similar with Mythic Sylvanas.
Sylvanas is alive and well for now, and we will see how the rest of her story plays out as Mythic Sanctum of Domination opens up on July 13.
