We already got to know the main antagonist of the Shadowlands add-on when the add-on was first officially announced at BlizzCon 2019. The Jailer was introduced to us quite enigmatically. At the announcement we could also see his silhouette, but now he looks a little different.
The previous week saw the release of Shadowlands and with that we were able to learn a little more about the character.
The overseer's name is Zovaal and he belongs to the pantheon of Eternal Ones (org. Eternal Ones). The Eternals are somehow connected to the First Ones, who probably created the Shadowlands and the entire Warcraft universe.
In addition to the Jailer, the members of this pantheon include:
The Shadowlands Collector's Edition of the Art Book includes this quote:
"The veil between realms wanes. The Helm of Domination was created to be our way forward. Instead, the one seared by the flames of life uses it to keep us at bay."
We don't know who is saying these words. Perhaps the Jailer himself, or perhaps one of his servants.
Jailer has characters like Sire Denathrius, Helya, Mueh'zala, Kel'Thuzad and of course Sylvana on his side.
Sylwana has been working with him since she jumped from the Crown of Frost in the Wrath Of The Lich King supplement.
It was he who directly or indirectly set Sylwane up as the new War Chief of the Horde by manipulating the dying Vol'jin.
All of the decisions Sylwane made were with the goal of delivering as many souls to the Horde as possible.
Zovaal turned his chains into a weapon with which he defeated Primus.
He probably would not have succeeded without the power from the "broken death machine".
The Shadowlands add-on has only just launched, so we'll learn more of the story as we get more updates, raids, etc. If you think a detail should be added, leave a comment under the Facebook post.
