With the first tier of this newest expansion, players will be able to experience Midnight's epic story across 3 different raids:

>The Voidspire: A 6-boss raid within the Voidstorm that serves as Xal'atath's stronghold.
>The Dreamrift: A single boss raid that takes players to a place where the veil between primordial dreams and brutal reality is thin.
>March on Quel'Danas: A 2-boss raid with large story spoilers.

Developers mentioned that The Voidspire and March on Quel'Danas raids are going to be significant to the endgame story of Midnight, with one raid leading directly into the other. Regarding the release schedule for these raids, the Voidspire and the Dreamrift raids will release at the beginning of the first season of Midnight, with The March on Quel'Danas raid releasing later.

While the exact timeline is still TBD, developers mentioned The March on Quel'Danas releasing roughly 2-3 weeks after the first two raids. Players can still expect all of these raids to release as a part of the first season/tier of Midnight.
