Introduction

The Horus Heresy, one of the defining moments in the 40K universe, presents a fascinating scenario where loyalists and heretics switch sides. This hypothetical question challenges us to envision a drastically different outcome, where the opposite Primarchs fell to Chaos. In this alternate universe, the Loyalists would now be Heretics, and the Heretics would be Loyalists. This essay explores the potential consequences of such an event, particularly by considering how the upbringing and growth of each Primarch could have changed, and the impact on the Imperium's future.

Alterations in Primarchical Upbringing and Growth

The key to understanding the potential outcomes of this alternate scenario lies in the upbringing and growth of each Primarch. The Primarchy experiences a wide range of experiences and challenges that shape their personalities and worldview. However, if the Primarchs who fell to Chaos were the Loyalists and vice versa, the following outcomes could have occurred:

Roboute Guilliman: As a young Primarch dedicated to the greater good of the Imperium, if he were on the side of Chaos, Guilliman might have embraced a more extremist worldview. This alteration could lead to a more aggressive push for reform, possibly leading to the collapse of the traditional bureaucratic structures within the Imperium. Lion El'andon: If the Lion, known for his unwavering loyalty and courage, were to have fallen to Chaos, he could have become a prominent warlord, initiating a widespread insurrection against the Imperium. His charisma and martial prowess would make him a formidable opponent. Sa-Micius: The Primarch of the Iron Warriors, who is known for his cunning and ambition, could have transformed into a ruthless factional leader. This shift would result in increased corruption and treachery within the Imperium's military structures. Lorgar: If Lorgar, the founder of the Word Bearers, was a Loyalist, he might have adhered strictly to the Word and become a rigid custodian of the Imperium's moral and spiritual values. This might have stifled innovation and dissent within the ranks of the Space Marines.

Choice of the New Arch Traitor

The choice of the new Arch Traitor would have significant implications for the conflict. With the Loyalists aligned with Chaos, Horus remains a strong contender for this role. Horus, with his charismatic leadership and strategic prowess, could rally the majority of the Primarchs to his cause. However, his fall into Chaos might have been more expansive and devastating, potentially leading to a complete breakdown of the Imperium.

Other potential Arch Traitors include:

Detritus: The leader of the Night Lords, Detritus, could have become a pivotal figure. His focus on darkness and shadow could have fueled an insidious and covert assault on the Imperium. Thrax Gorgon: The leader of the Alpha Legion, if he were to become a Loyalist, might have had a different approach to the conflict, possibly using psychological warfare and espionage to undermine the Imperium from within. Lucius: If Lucius, the admiral of the Imperium's fleet, fell to Chaos, he could have turned the tide of the conflict by leveraging his resources to control key strategic points and disrupt the Imperium's supply lines.

Selection of New Champions

The gods of the Imperium may have chosen different champions in this alternate scenario due to the shift in the Primarchs' allegiance. The following scenarios are considered:

Sanctus Seppelax: If the Emperor were to lose the heresy, despite the new alignment, he would likely continue to seek ways to mitigate the chaos and restore stability. The selection of Sanctus Seppelax, a high priest of the Imperial Cult, could have focused on spiritual and ideological reforms to counteract the new Traitors. Vul Canasi: Alternatively, the Emperor might have chosen Vul Canasi, a powerful psyker, to detect and counter the Fultine the Fool: Known for her unconventional approach, Fultine might have been chosen to seek out and sabotage the efforts of the Traitors through her unorthodox tactics and strategic mind.

Impact on the Imperial Decline

The ultimate consequence of this alternate scenario remains unclear. While most alt heresies predict a decline of the Imperium, it's possible that the balance of power could have shifted in a way that prevents an outright collapse. The ongoing decline, however, would likely be exacerbated by the internal strife and potential betrayal from the Loyalists themselves.

It's worth noting that this scenario is purely speculative and falls into the realm of fan fiction. It challenges the traditional narrative and forces us to reevaluate the Horus Heresy in a more fluid and complex manner. The 40K universe, with its vast and intricate lore, lends itself to such imaginative explorations, allowing us to delve into the potential outcomes of different scenarios.
