The main antagonist of Shadowlands was already known to us when it was announced at BlizzCon 2019. The Jailer was presented to us in a very mysterious manner. We could see his silhouette at the announcement, but he now looks a little differently.

Shadowlands was released the week before and we were able learn more about the character.

The overseer's name Zovaal is Zovaal, and he is part of the pantheon Eternal Ones (org. Eternal Ones. The Eternals are somehow related to the First Ones, who most likely created Warcraft's Shadowlands and the entire Warcraft universe.

This pantheon includes:

  • ARBITER – He was the one who ruled over the souls that ended up in the Shadowlands after their deaths. His insanity caused the anime crisis as well as the corruption of "death machine".
  • KYRESTIA – He leads the Kyrians on the land of Bastion.
  • KINGDOM OF THE COLD - Cares for the All-New and leads Night Fairies. She refers to Yser as "her sister's pet", which could indicate that Elune is her sister.
  • DENATHRIUS – He is the creator of Revendreth and its leader.
  • PRIMUS - The Maldraxxus' lost founder and ruler.
  • Zovaal was once a disciple the Arbiter.
  • Both the Supervisor as well as the Arbiter have a similar hole on their chests. Except that Zovaal's hole is empty and the Arbiter has a pearl in it.
  • His fellow human beings were forced to lock him up in the Hells for treason.
  • We don't know what the Supervisor did to cause anger among the Pantheon. We've seen the effects of his actions on Warcraft, and it had an impact on the entire universe.
  • Primus believes that Zovaal wasn't acting alone at that time and that he had allies.
  • Zovaal was a prisoner of Vale but also its overseer and kept the souls of the most vile beings in Torghast.
  • He abducted Runecarver, and ordered him to presumably create both the Helmet of Domination (or the Frost Blade). In the movie Beyond, Devos called them "the weapons for the Vale". The Blade's runes match his body runes.

This quote is included in the Shadowlands Collector's Edition of the Art Book:

"The veil between realms is fading. The Helm of Domination was designed to help us move forward. Instead, the one suffused by the flames and life uses it to keep us at bay."

We don't know the person who is saying these words. Maybe the Jailer or one of his servants.

Jailer has Sire Denathrius and Helya as his characters, along with Kel'Thuzad, Mueh’zala, Kel’Thuzad, and Sylvana.

Sylwana has been with him since she jumped from Crown of Frost in Wrath Of The Lich King.

He was the one who, directly or indirectly, made Sylwane the War Chief of Horde by manipulating dying Vol'jin.

Sylwane made all of her decisions with the intention of delivering as many souls as possible to the Horde.

Primus was defeated by Zovaal when Zovaal transformed his chains into a weapon.

Without the power of the "broken Death Machine", he would have probably failed.

Shadowlands is just being launched. We'll continue to learn more about the story as we receive more updates, raids, and so on. Comment below the Facebook post if you feel a detail should be included.
