Kull was a barbarian. He used the word himself. He was born in Atlantis when Atlantis was a pre-Hyborian island kingdom of warriors and exiles, ran from Atlantis after a falling-out the Atlantean records did not preserve, and eventually walked into Valusia alone, broke, and angry — and within a few years was the king of it. The Bureau's interest in Kull is not that he conquered a pre-human kingdom. The Bureau's interest is that, after he conquered it, he was the first documented human in the archive to look at his own court, recognize that several of his advisors were not what they appeared, and do something about it.

The action he took is the founding precedent for every counter-infiltration operation in the file. The Bureau has never canonized him — there is no portrait on any wall — but the methodology survives in current procedure, and the procedure can be traced, link by link, back to a single night in a Valusian audience chamber roughly a hundred thousand years ago.

Origin

Atlantis, in the Thurian Age: long before the Atlantis that sank in Lovecraftian timelines, and long before the Atlantis that Howard would later document in his Conan dispatches as a memory the Cimmerians carried in their bones. The Thurian Atlantis was an island kingdom of barbarian warriors, hierarchical and brutal. Kull was born into a clan, exiled from it as a young man for reasons that did not survive in the records, and spent his early adulthood as a wandering fighter: a sailor, a pirate, an arena gladiator in Valusia, and finally a captain of the Valusian royal guard. The trajectory is unusual but not unprecedented. The Thurian world had room for foreign mercenaries to rise. It did not usually have room for them to rise to the throne.

The Conquest

The Valusian throne was vacant. The previous king had died without a clear successor and the Serpent Men in the court were maneuvering to install a puppet. Kull intervened: directly, with a small group of loyalists, and with the kind of decisive personal violence that the late Valusian aristocracy was no longer prepared for. Within a single night he was the king. Within a week the surviving aristocracy had either accepted the new arrangement or been quietly removed. The transition, by Thurian standards, was orderly. By any other standard it was a slaughter. Kull did not distinguish between the two.

The Discovery

Several years into his reign, during a private audience with one of his most trusted advisors, an attempted assassination revealed the advisor's true form mid-strike. Kull survived. The advisor did not. Kull, in the days that followed, conducted what the Bureau considers the first systematic counter-infiltration operation in the human archive. He identified (through observation, interrogation, and the deliberate use of dream-sensitive members of his retinue as detection equipment) at least eleven Serpent Men in his court. He killed all of them personally. He did not delegate. The Bureau has noted, with some discomfort, that the methodology was sound: he trusted only the people whose dreams he had personally heard, he confirmed each identification with a second sensitive before acting, and he carried out the executions in private to deny the surviving Serpent Men a public warning.

The operational logic is recognizable. It is the logic the Bureau still uses, with better instrumentation and worse results.

Aftermath

The purge bought Valusia a generation of stability. It did not solve the problem. The Serpent Men withdrew, regrouped, and resumed their infiltration through new agents. By the end of Kull's reign (and the records on his death are sparse, but suggest he died in battle late in life, against E̒̒ꫀA͌Ġ̳ꫂǏ͒̚C̢͋͗Y͆ͅN͗̅͝X̊̄𓆙ꫀĢ̏𓆙W̡̧͌) the court was already showing signs of re-infiltration. Kull's heirs lacked his sensitivity. They lacked his willingness to suspect the people closest to them. The kingdom slid back into its previous condition within a few decades, and within a few generations Valusia was once again a Serpent Men operation wearing a human crown.

Kull seems to have understood this would happen. The records (the fragments of them that came through Howard's reception) suggest he died grimly, expecting nothing, confident in nothing except the small and temporary good he had managed to do. This is consistent with the broader Atlantean temperament his Cimmerian descendants would inherit. It is also consistent with the Bureau's experience of every counter-infiltration officer who has lasted more than a decade in the field.

Assessment

Kull is in this directory for one reason: he was the first. The first human to look at the things wearing human faces and refuse to be fooled. Every investigator in this directory who has ever pulled a Serpent Man, a Mi-Go imposter, or a Shoggoth mimic out of a position of trust is operating in a tradition that begins with him. The records do not call him a hero. The records call him a king who killed his advisors. The Bureau's position is that those are the same thing.
