In the year 99, a catastrophe known as the Calamity of 99 struck the Olmoy civilization living in the Valley of Exiles around Lake Kuk’ul’kaan. This disaster unfolded suddenly and brutally, decimating the three main cities—Chak Lu’um, Abarraneand Muun Tok—as well as K’uhul Tuun, the island city dedicated to the Olmoy’s ancestral deities. A volcanic eruption from the eastern Land of Ash and Smoke released a toxic wave of superheated gases and ash that rolled through the valley, suffocating its inhabitants and turning a once-thriving community into a haunted ruin in a matter of hours.
Prelude to Disaster
For years leading up to the eruption, minor tremors and sulfurous smells had seeped into the valley from the Land of Ash and Smoke. The Olmoy people, descendants of a once-powerful civilization, had adapted to the valley’s volcanic activity and the faint tremors were seen as natural occurrences, something they lived alongside. Priests in K’uhul Tuun had observed strange omens—clouds that gathered but never rained, unsettling visions during rituals, and eerie lights glinting on the lake’s surface at night—but these warnings went unheeded. The Olmoy interpreted them as signs of divine power, yet failed to understand their true meaning.
There were a few, however, who saw the signs more clearly. High Priest Chaac Ixim, one of the last true priests of K’uhul Tuun, had voiced his concerns, interpreting the omens as a warning from their forgotten gods. But in the isolated city of K’uhul Tuun, far removed from the bustling lives of the lakeside cities, his warnings were dismissed as mere superstition. This misinterpretation of the gods’ signs would prove fatal.
The Eruption
In a violent display of the earth’s fury, the volcanic peak east of the valley erupted with a force not seen in generations. Shortly after midnight, the first wave of seismic tremors rattled the ground, waking the valley’s inhabitants from their slumber. The mountain then released a massive plume of ash and deadly gases, creating a pyroclastic surge that swept westward toward Lake Kuk’ul’kaan. The advancing cloud of hot gas, steam, and volcanic ash hurtled through the valley, consuming everything in its path.
The Olmoy cities, surrounded by sheer cliffs and mountains, had nowhere to escape as the superheated cloud filled the valley, settling upon the cities like a shroud of death. Houses made from stone offered little protection against the blistering heat and suffocating fumes. In Chak Lu’um, people fled to the shore, hoping the lake would offer shelter. Some tried to escape by boat, but as the gases settled over the lake’s surface, the few who made it into the water suffocated before they could row more than a few yards from shore.
In Abarrane, famed for its herbalists and healers, the people attempted to use their medicinal herbs in desperation to counteract the fumes, creating makeshift coverings and masks. But no remedy could counter the raw power of the gases seeping into their city. Death came swiftly, robbing breath from the strongest warriors and the most resilient shamans alike.
In Muun Tok, the city of obsidian, priests of darker rites prepared to perform rituals to dispel what they believed was a curse. They lit sacred braziers, hoping to burn away the evil they thought had come to test their resolve. But the black smoke of their rites mixed with the toxic cloud descending upon the city, and Muun Tok’s people were among the first to perish, their breath stolen by the very fires they had trusted.
On K’uhul Tuun, the island city, the priests and oracles gathered at the unfinished ziggurat, chanting to their gods and praying for salvation. As the gases reached the island, their voices faltered, and the cries of their followers fell silent. The priests died clutching the ziggurat’s steps, still trying to complete rituals to shield the city even as they gasped for breath.
The Deadly Cloud: The Effects of the Gases
The volcanic gases, rich in carbon dioxide, sulfur dioxide, and other lethal vapors, filled the valley with a dense, suffocating fog. The gases choked out the very air, causing instant suffocation for those caught within it. The superheated steam seared flesh, while the thick ash that followed covered the cities, preserving them under a layer of gray that would later harden into stone. The entire event took only a few hours, but by dawn, the cities around Lake Kuk’ul’kaan were silent, frozen in a layer of volcanic ash and gas, every life extinguished.
The Transformation of the Valley
As the Calamity of 99 faded, what remained was a transformed valley. The eastern region became known as the Land of Ash and Smoke, a desolate wasteland poisoned by volcanic gases that lingered in the air, making it deadly to any who entered. The blackened earth was sterile, with few plants or animals willing to cross into its boundaries. The valley itself, however, seemed protected from further destruction, as if held in stasis by some unseen force—likely the same dark magic emanating from the unfinished ziggurat of K’uhul Tuun.
Lake Kuk’ul’kaan, once a symbol of life and the heart of Olmoy civilization, was now haunted. The lake’s waters had been tainted by ash and the remnants of those who had tried to escape into it, and over the years, eerie lights would often be seen flickering across its surface, stirring rumors of restless spirits and unquiet ancestors.
The Legacy of the Calamity
The Calamity of 99 not only annihilated the Olmoy’s last significant settlements but also extinguished their hopes of restoring their civilization. In the centuries that followed, the ruins around Lake Kuk’ul’kaan became a place of mystery and dread. Explorers and adventurers drawn to the valley would occasionally disappear, never to return, fueling legends of vengeful spirits, cursed ziggurats, and the unfinished magic of K’uhul Tuun’s totems.
Today, few dare to approach the Valley of Exiles, and even fewer venture into the Land of Ash and Smoke. The ruins stand as a ghostly testament to the Olmoy’s final days, their abandoned ziggurats crumbling but ever silent, preserving the memories of a once-great people who believed they could escape the doom that had been waiting in the heart of their empire.
