The Age of Roboute Guilliman in the 40K Universe Prior to Stasis

The Warhammer 40,000 universe is a complex and intriguing world filled with powerful beings, including the Primarchs, who are the sons of the Emperor. Among them, Roboute Guilliman, the Primarch of the Ultramarines, stands out as a key figure. But how old was Roboute Guilliman before he was placed in stasis? This article aims to explore the timeline and provide insight into Guilliman's age before his entombment.

Birth and Early Life

Roboute Guilliman was born in the year 40,000 of the Terran calendar, which corresponds to the year 1 of the Imperium M31. As one of the twenty Primarchs, he was found by the Emperor on the planet Macragge during the Great Crusade. He was roughly 100 years old at this time, a modest age for a Primarch. However, the exact details of his birth and early life are not explicitly stated, making it difficult to pinpoint his precise age.

Conquest and Leadership

According to historical records, Guilliman was remarkably gifted from a young age. By the time he was only ten years old, he had mastered all the teachings of his tutors, eerily reminiscent of Alexander the Great. His early conquests or unifications of Macragge suggest that he spent a considerable amount of time there, likely more than a decade.

After mastering his education and unifying Macragge, Guilliman continued to lead as the ruler of the planet for an extended period. It is believed that he ruled for multiple decades, possibly even a century, before the Emperor arrived and recruited him. This lengthy tenure as a ruler places Roboute Guilliman somewhere between 100 and 200 years old at the time of his recruitment.

The Current Timeline and Time Displacement

With the passage of time, Guilliman played a crucial role in the development of the Imperium and the Great Crusade. He later implemented the Second Founding, breaking up the legions into smaller Chapters. After serving as the leader of the Ultramarines for an additional hundred years, he faced his ultimate fate at the hands of Fulgrim during the Horus Heresy.

The timeline between 792.M30 (29792 AD) and 121.M31 (30121 AD) places Roboute Guilliman at around 329 years old. However, this calculation assumes a constant and universal time across the galaxy, which is not the case. Chaos, in particular, has been known to manipulate and alter the flow of time through the Warp.

The Debate on Guilliman's Age

Given the complexity of the timeline, especially due to the Horus Heresy and the later stasis, there are varying opinions on Guilliman's exact age. Some argue that he could be closer to 400 years old when he was put into stasis. The uncertainty arises from the fact that time isn't universally consistent across the galaxy. The chaos god Tzeentch, for example, has been known to alter time-based mechanics, making it difficult to pinpoint an exact age.

While there is no definitive answer, the debate around Roboute Guilliman's age highlights the intricate nature of the Warhammer 40,000 universe and the challenges of maintaining a consistent timeline. Whether Guilliman was 100, 200, or 400 years old, there is no denying his significant impact on the Imperium and its ongoing struggle against the forces of Chaos.
