NEW ZONE: ZERETH MORTIS
Zereth Mortis was created by the First Ones, and it's intended to create afterlives. Its denizens—the automa—have created all that exists in the Shadowlands, Azeroth, and realms beyond. It is a strange, alien location that defies all concepts of reality or physics. The Jailer intends to use Zereth Mortis' power to reshape everything according to his design.
The Jailer is able to open a portal to who-knows-where, taking Anduin with him, and the Primus had us take some time to retrieve some new sigils. Now, we have gathered our forces, we're working with the Primus to open our own gateway to pursue the Jailer to this realm unlike any we've seen before.
The Primus opens a portal and we come in to this alien land. It's completely white, foggy, we're walking on water for some reason... They can only make out some shapes, some figures there, some crazy devices and consoles, eventually making their way to a giant gate and behind it, lies Zereth Mortis.
Zereth Mortis was created by the First Ones and it is intended to create afterlives. Think of it as being tucked away in the fabric of the Shadowlands itself. It's kinda the behind the scenes of these afterlives that we've journeyed to. It's the land where the progenitors, the First Ones who created all of the realms of the Shadowlands, this is their workshop. They created everything we experienced in Azeroth, the Shadowlands, and even realms we haven't discovered yet. These First Ones built the universe, as far as we know, but their intentions and methods are completely unknown.
But of course the Jailer's presence here is disrupting this process, and we're working to pushback against the Jailer's forces and protect this place.
