The rebirth of Ultramar is Roboute Guilliman’s grand plan to restore the Ultramarines’ realm to its pre-Heresy borders of 500 worlds. It’s a massive military campaign, the Ultramarian Reclamation, fought in the aftermath of the Great Rift and the Plague Wars.
What the rebirth of Ultramar means
When Guilliman returned and launched the Indomitus Crusade, he also declared that Ultramar would be restored to its original size: 500 worlds. Many of those planets were already Imperial but needed negotiations to transfer control. Others were lost or occupied by heretics and xenos after the Great Rift tore the galaxy apart.
The goal wasn’t just to reclaim lost territory. It was to rebuild a functioning, self-sufficient realm that could serve as a model for the Imperium. In practice, the campaign would bring far more than 500 worlds under Ultramar’s banner.
The four-front strategy
Guilliman, busy leading the Indomitus Crusade, still planned the reconquest. He launched four primary offensives from the Tetrarch worlds: Konor in the north, Andermung in the south, Vespator in the east, and Protos in the west.
Each front would seize key planets and resources first, then auxiliary armies would move in to occupy the region. The idea was to create a rapid speartip followed by solid consolidation.
Who’s leading the fight
With Guilliman away and Marneus Calgar returning from the Battle of Bastior, command fell to several Ultramarines captains. Demetrian Titus, Mikael Fabian, Uriel Ventris, and Ferren Areios were among those tasked with executing the campaign.
They were supported by Tetrarchs like Decimus Androdinus Felix, Balthus, Portan, and Severus Agemman, along with other Imperial forces.
- Captain Demetrian Titus (2nd Company)
- Captain Mikael Fabian (3rd Company)
- Captain Uriel Ventris (4th Company)
- Captain Ferren Areios (6th Company)
- Tetrarch Decimus Androdinus Felix
- Tetrarch Balthus
- Tetrarch Portan
- Tetrarch Severus Agemman
Enemies and ongoing conflict
The Ultramarian Reclamation isn’t a clean fight. Imperial forces face a mix of Necrons, Orks, Tyranids, Genestealer Cults, Eldar, Chaos warbands, and even Leagues of Votann. Notable threats include the Nekrosor Ammentar and the Oblivion Court, as well as Hive Fleet Leviathan.
As of M42, the outcome is still ongoing. The campaign has seen heavy casualties, and the Imperium hasn’t yet achieved total victory.
