In the nascent days of Embergrave, the First Age dawned, an era where the veil between the material realm and the ethereal Sway was fragile and permeable. The world, young and untested, witnessed humanity in its formative years. The Inner Isles of Hadavi, cradles of civilization, were home to tribes who lived in deep harmony with their surroundings, their existence intertwined with the rhythms of the natural world.

These early societies, thriving in the heart of Hadavi, were akin to verdant oases amidst a wilderness of untold mysteries and dangers. Tribal cities, rich in culture and tradition, dotted the landscape, each a testament to humanity's burgeoning connection with nature. Over time, these tribal communities explored the world and evolved, giving rise to ancient cities and empires, their influence spreading like a tapestry across all of Hadavi.

However, the First Age was not just a time of growth and discovery; it was an era besieged by otherworldly incursions. The Sway, a realm of boundless chaos and creation, spilled its inhabitants into the material world. This invasion was not of a singular kind but a kaleidoscopic array of entities from thousands of worlds brushing against Hadavi. Among these were enigmatic shapeshifters, demonic beings with infernal desires, devilish tricksters weaving plots of corruption, and fae-like entities whose whimsical yet often malevolent nature challenged the very fabric of reality. Humanity, in its struggle to survive, faced not only these threats but also the task of unifying its disparate tribes and empires.

The heroes of this age, born of necessity and courage, rose to confront these challenges. Often they ventured into the sway, some completely consumed by the otherworldly nature beyond the veil. Though, their battles were not only against the forces of the Sway but also for the unity of their people. They forged alliances with the natural world, embracing the elements and the creatures of Hadavi as allies. Together, they pushed back against the tide of otherworldly invaders, their efforts a symphony of human resilience and the wild's untamed power.

As the First Age progressed, the burgeoning civilizations of humanity stood as bulwarks against the Sway, their expanding empires a testament to their triumph over the chaos of the other realms. The age of tribal chiefdoms transitioned into a golden age of empires, laying the groundwork for the emergence of the Kings of Rapture, and their central figure: Kunjirmos the Shimmer King
