Dawn of War Wiki

Jonah Orion is a powerful psyker, able to use psychic tomes and relics to wield a variety of combat abilities. With the right traits and equipment, he can be effective in almost any battlefield role.

The Space Marines psykers known as Librarians are able to manipulate the fabric of the Warp itself. They are both powerful warriors and lore keepers for their chapters.

Jonah Orion has served under Gabriel Angelos since the aftermath of the Tartarus campaign. During the Tyranid invasion, he was one of the psykers tasked with battling the mighty Hive Mind as Captain Angelos made for sub-sector Aurelia.

Of the dozen Librarians, Navigators and Astropaths accompanying Angelos, only Jonah survived.

Chaos Rising[]

Compared to the other possible units, Jonah is a rather difficult one to use. He focuses more on abilities than raw combat power, so you'll regularly have to manually fire his abilities to get the most out of him. He is also by far the most fragile of all of the squads, even more than Cyrus; Jonah is just as lightly armored as Cyrus but he is permanently a one-man squad, and a number of larger enemies can kill him in one or two hits. He will need to very liberally use abilities like Force Dome to be able to survive very long, and overall needs extensive micro-management.

Depending on the player's choices and deeds during the missions, as well as choices of wargear, Jonah could be revealed as the traitor. This reveals that during the final battle against the Hive Mind, Jonah was weakened enough for a daemon to possess him, despite the protection provided by his wargear after that it was a downhill battle, and eventually the daemon succeeded in possessing Jonah's body. Shortly afterwards, the Force Commander led his remaining squads in a mission to kill the daemon and free Jonah.


Jonah Orion returned to the side of Gabriel Angelos after the events of Chaos Rising, apparently serving as his primary advisor. During the events of Retribution, Jonah followed Gabriel in his ill-fated attempt at defeating the daemon prince Kyras, becoming grievously wounded in the process but miraculously survived.

Dawn of War III[]

Librarian Jonah Orion

Jonah Orion is the Blood Raven's Chief Librarian and a man of fearsome psychic power. Focused on supporting his brethren, he is a flexible Elite who amplifies the effectiveness of his allies.

Although he sustained what many thought was a mortal wound on Cyrene, he miraculously survived. Understanding the gravity of Jonah’s sacrifices for the Chapter and his undeniable role in their victory against Arch-Traitor Azariah Kyras, the newly appointed Chapter Master Gabriel Angelos promoted him to Chief Librarian.

Now, it is Jonah’s desire to redefine psyker culture within the Blood Ravens Chapter so that heresy can’t breed within. Due to their gene seed, the Blood Ravens will always have a higher distribution of psykers. It is Jonah’s duty as Chief Librarian to ensure that they don’t stray.

The Chief Librarian’s abilities interact in a couple of different ways. Casting Fury of the Ancients inside of Stonewall will cause it to fill the area instead of casting in a line. Using this combo, Jonah is great at trapping enemies and dealing considerable damage. Casting Emperor’s Light inside of Stonewall will make Emperor’s Light last longer. "Stonewall can block off escape routes, lay traps, and set up other abilities."

Stonewall can block off escape routes, lay traps, and set up other abilities. It also makes for a great escape tool, as Jonah can use it to block incoming damage and use Fury of the Ancients to speed his allies out of harm’s way.

Jonah can be countered by skimmer units such as Land Speeders since they can chase him down quite easily. Units that can jump or teleport are able to infiltrate Stonewall, so you’ll need to be careful about when you use it. Similarly, artillery barrages aren’t blocked by Stonewall, so make sure you don’t accidentally lock your allies in the midst of enemy fire.
