As far as we know, the flow of souls was disrupted during the events of the Broken Shore, except Ursoc was able to reach Ardenweald as we have seen in the video dedicated to him. Is he an exception? Is it an intervention of Elune or is it related to the Emerald Dream or to his status as a Wild God?
When Ursoc was slain in the Emerald Nightmare, souls were still being judged by the Arbiter.
This would mean that likewise Ysera died when the Arbiter was still sending people to Ardenweald.
As for when exactly the Shadowlands broke, supposedly we will be learning that soon:
- You mentioned this in a previous interview, but since when exactly has the flow of Azeroth’s souls been completely diverted to the Maw? You mentioned the Broken Shore. Would it be around that time? Was the flow of souls from other worlds diverted at the same time or was it long ago?
To be clear, nothing has stopped the flow of souls from Azeroth or any other world from entering the Shadowlands. What has changed is that the Arbiter is no longer judging souls and sending them to their appropriate afterlives; instead, they are all going to the Maw.
The exact moment this happened, along with some clues as to why, will be revealed in an in-game cinematic that you can view in Oribos after the expansion launches.
