Granted unparalleled autonomy by a secret pact with the Ultramarines Division, Cawl's genetic creations and mechanistic innovations led to many of the Space Marines' most famous divisions borrowing from him. Most importantly, he helped create the Primaris Space Marines, an entirely new race of soldiers.

Unrivaled in knowledge and ingenuity, this Archmagos Dominus of the Adeptus Mechanicus has endured countless centuries dedicated to understanding, mastering, and perfecting technology. Its influence spans over ten millennia, from the dark days of the Horus Heresy to the grim future of the 41st Millennium.
Cawl's life's work is the spectacular Primaris Space Marines, which were an evolutionary leap for the defenders of the Empire, providing a glimmer of hope in an age of darkness and despair. Always trying to push the boundaries of what others would dismiss as heretical, he even dared to improve the Emperor's original drafts, which was considered taboo and could easily provoke accusations of technoheresy. Beyond technology, Belisarius Cawl's contributions to politics and warfare are immeasurable. He single-handedly strategizes and directs forces that can determine the fate of entire worlds. His ambition, brilliance, and most of all, resilience helped humanity overcome the grim darkness of the Warhammer 40,000 universe.

As Archmagos Dominus of the Adeptus Mechanicus, Cawl is the epitome of scientific genius, his mind crystallized in arcane technologies to gain unprecedented insight into the grand design of the universe.
Born on Mars in the late 30th millennium, Cawl was inducted into the Cult Mechanicus at a young age and quickly learned many of the machine's secrets. In the 10,000 years following the Horus Heresy, he toyed with bioalchemy and cybernetics, constantly improving his skills. On many occasions, Cawl circumvented the strict doctrines of the Mechanicus by exploring forbidden technologies and knowledge that many of his colleagues considered heretical.

His glory remains in the Primaris Space Marines, an unprecedented triumph of genius where Cawl improved upon the Emperor's original plans, giving birth to warriors of unparalleled strength and resilience. This achievement was not without controversy, as many considered it too big a step, a bold challenge to the emperor's omnipotence.
But Cawl is often shrouded in mystery, with many chapters of his past closed even to himself.

Creator and overseer of the Primaris Space Marines, Cawl contributed to the Ultima Foundation, the great awakening of the Astartes that followed the fall of Cadia. Despite being over ten thousand years old, Cawl's great age does not hinder his innovation and ingenuity. In fact, it only enhanced his skills; making him the galaxy's foremost authority on genetic engineering and the biological sciences.
Cawl's achievements not only directly led to the creation of the Primaris Space Marines, a new race of warriors designed to be more powerful than their predecessors, but also recovered several lost technologies and artifacts from humanity's distant past.

Character Profile

Belisarius Cawl is the revered Archmagos Dominus of the Adeptus Mechanicus, the highest priest of the Technic Empire. For more than ten thousand years his disciplined mind followed an unbroken thread of study and experimentation. Cawl was born before the Horus Heresy, an age of rebellion that crippled human civilization. Thus his service to the emperor spans the entire history of the empire.
Cawl's most notable work is the creation of the Primaris Space Marines, a new race of soldiers genetically enhanced from their predecessors. However, his brilliance is underestimated by many because his reckless pursuit of understanding technology is completely at odds with the dogma of mechanics.
Despite his advanced age, Archmage Dominus Cawl still has an insatiable curiosity about the universe. With his solar blaster and masterful power axe, he deftly demonstrates that his prodigious intelligence is matched only by his combat prowess. Cawl's personal security is supplemented by numerous armed men, bodyguards and automated defense systems.
Resisting fear and seemingly at the same time, some speculate that the masterful Belisarius Cawl is no longer fully human. Some believe that his body is a shell, powered by machines, and that his brain is a repository of Imperial knowledge, aided by the most mysterious and forbidden technologies. Undeterred by the rumours, he remains steadfastly committed to his investigation, obsessed with the future of the empire.

Story Arc

Belisarius Cawl, Archmagos Dominus of the Adeptus Mechanicus and chief architect of the Empire's future, plays a central role in the vast Warhammer 40,000 universe. Its story takes place about 40,000 years in the future and basically revolves around the main mission.
In order for humanity to survive and thrive in a war-torn universe, Cawl was given an impossible task by Primarch Roboute Guilliman: to create a new race of Space Marines that would better deal with the many threats facing humanity. This led to the creation of the Primaris Space Marines, warriors of exceptional strength, nobility and courage.
Despite being 10,000 years old, Cawl was ambitious and innovative. He pushed the boundaries of technology and morality, often clashing with the restrictive and conservative Adeptus Mechanicus. Cawl's quest for illicit knowledge led him to delve into ancient and dangerous technology and create marvels of war machines.
However, its plot is not only about technological innovations. It also focuses on domestic politics. Cawl's controversial practices made him many enemies. But the dark political work within the Mechanicus never deterred his quest to improve the empire. Instead, he used them to his advantage, outmaneuvering opponents and killing dissent with deft wit.
