Yep.
She has been given a redemption task that needs an end.
And not be 10000 years like Illidan. Souls need to be saved and it be really jacked up if we leave them suffering for 10K years.
Or they will put our time is different than the shadow lands. Which already has an issue. We know its the same time scale.
Millenia were not skipped on the SL deployment. We had 2 years there. we came back to azeroth 2 years later.
She ahs souls to save from eteranal damnation. If not a reveal by the end of TWW…the next 2 expacs she has to comeback.
since we can’t have 1 billion sould still suffering in 6 years game time. That make the running joke did the devs forget about the sword in silithus look mild by comparison.
