For anyone else lost, this had a bunch of prerequisites post main campaign:
- The Beginning of the End
- Socialized Medicine
- Rules and Consequences
- A Spy Like Us
- Defense of the People
- Make Them Prey
- A Shot at the Top
All starting at Executor Nizrek at 52.88, 46.29 in The City of Threads, Azj Kahet.
Once those are complete, you can accept To Kill a Queen, which then lets you talk to Kriz the “Loyal” at 31.61, 63.97 in The City of Threads, Azj Kahet to enter the raid in story mode.
Would’ve been nice if this was easier to find.
