The Unification Wars are often treated as a distant, mythic prelude to the Imperium—a bygone era of techno-barbarians and the Emperor’s first conquests. But as this episode of Adeptus Ridiculous makes clear, the nightmare of Old Earth was far stranger, more brutal, and more foundational than the sanitized imperial histories admit. Before the Space Marines, before the Great Crusade, there was only anarchy, bloodshed, and the slow, methodical rise of a warlord who would become a god.

The Nightmare of Old Earth

After the fall of humanity’s golden age and the 3,000-year cybernetic revolt of the Men of Iron, the galaxy was plunged into the Age of Strife. Terra, the cradle of humanity, became a post-apocalyptic wasteland ruled by techno-barbarians. “Terra got Mad Maxed,” as the hosts put it. Over centuries, countless unremembered empires rose and fell, their conquests becoming myth almost instantly. Among the most horrific tyrants was the Unspeakable King of Albia, who nearly unified the planet and was served by a cadre of female nulls called the Hollow Ones—believed to be the echoes that would later inspire the Sisters of Silence. His final descendant, Narthan Doom, was the last tyrant of the Pan-Pacific Empire, and his quote—“An ambition to save humanity is almost always a disguise for the desire to rule it”—is a fitting epitaph for the era.

Before the Great Crusade and the Horus Heresy, Terra was a post-apocalyptic wasteland. For over five thousand years during Old Night, humanity was torn apart by anarchy, war, and the horrors of the Warp. The planet was ruled by a nightmare rotation of feral nomads and oppressive techno-barbarians like the Unspeakable King. This week, the crew dives into the Unification Wars when the Emperor rises from the ashes to conquer Old Earth. For the very start, when Blood Angels were stalking battlefields as the cannibalistic "Eaters of the Dead", and Proto-Night Lords cast ten million innocent people into a chasm at Vhnori, the foundation of the Imperium was built on pure, unadulterated atrocities that culminated in the "final stand" of the Thunder Warriors at Mount Ararat—where the survivors of the Unification Wars were ruthlessly cut down by the Emperor's own Custodians.
