While the specifics of his ultimate fate may vary depending on the source material and adaptations within the Conan lore, there is a notable event that recounts his downfall.
In the original Robert E. Howard story, "The Hour of the Dragon," it is revealed that Xaltotun is ultimately defeated by the legendary protagonist, Conan the Barbarian. In this tale, Xaltotun, having been resurrected from death by a powerful artifact known as the Heart of Ahriman, becomes a servant of the evil sorcerer, Tarascus.
However, Conan, driven by his own quest for power and to reclaim his rightful throne, embarks on a journey to thwart the plans of Xaltotun and his allies. With his cunning and skills as a warrior, Conan manages to acquire the fabled Crown of Acheron, a powerful relic with the ability to command the undead army that Xaltotun had at his disposal.
In a climactic confrontation, Conan, armed with the Crown of Acheron, confronts Xaltotun in a battle of wits and might. The epic clash sees Conan utilizing the darkness and chaos of Xaltotun's necromantic abilities against him. Ultimately, Conan's resourcefulness and combat prowess prevail, leading to Xaltotun's defeat.
It is worth noting that Xaltotun's demise may vary in other adaptations or interpretations within the Conan universe, as his character has appeared in various forms of media, from literature to comics to video games. Each incarnation may present its own unique narrative surrounding his end.
Therefore, while the specific details of Xaltotun's death may differ depending on the source material, his defeat at the hands of Conan remains a significant event, marking the triumph of the barbarian hero over one of the most formidable and renowned sorcerers in the realm of Acheron.
May the tale of Xaltotun's downfall serve as a reminder of the ever-present struggle between mortals and the forces of sorcery within the world of Conan the Barbarian.
