where is alleria windrunner in midnight after she was defeated at the void spire raid

Alleria Windrunner’s apparent fate in Midnight after the Voidspire raid is that she is not confirmed dead ; the raid ends with her and Turalyon being teleported away, and later coverage says their fates remain unknown. In the same story beat, Xal’atath removes L’ura from Alleria, which suggests Alleria was a key vessel for that void/naaru power rather than the end of her arc.

Where she is

• She is not shown settling in a safe, named location after the raid.
• The available reporting says she and Turalyon are taken to an unknown place.

• So the safest answer is: her exact location in Midnight after Voidspire is unresolved.

What the raid implies

• The raid finale centers on Xal’atath using Alleria to reach L’ura, the dark naaru absorbed by Alleria in the past.

• After L’ura is torn out, the Sunwell is transformed into the Darkwell, and Alleria’s immediate fate is left open rather than clearly concluded.

Quick scoop

The current lore answer is basically: Alleria disappears from the scene, survives the encounter as far as we know, and her whereabouts are unknown afterward.

TL;DR: She is not confirmed dead; after Voidspire, Alleria is teleported away and her location is left unknown.
