Nestled near the banks of a winding river, the entrance to the Cave of Light is marked by the remnants of an ancient fortress bridge, crumbled and half-submerged in the water. Its once-grand structure, now in ruins, offers a stark contrast to the pristine mystery of the cave. Towering above, the Stormcast Eternals' fortress stands like an unyielding sentinel, guarding the surrounding lands with vigilant eyes, though the cave's secrets remain mostly unknown to its stalwart defenders.
The Cave of Light is not just an ordinary cavern, but a portal to a vast and complex network of tunnels that stretch far beneath the surface. Its winding passages and hidden chambers eventually connect to an expansive underground system that reaches deep under the volcanic heart of Volcano Esmir. The air inside is thick with the scent of ancient stone, and the walls glow faintly with an ethereal radiance, a light that seems to pulse with an energy older than time itself.
Though its name implies warmth and serenity, the cave is anything but peaceful. The deeper one ventures, the more intense the atmosphere becomes. It is said that these tunnels lead to a realm of wonder and peril—where the Seraphon, ancient and powerful beings of celestial origin, dwell. The Seraphon, with their enigmatic rituals and otherworldly presence, make the deepest parts of the Cave of Light a place of awe and mystery, where time itself seems to warp and shift.
The entrance by the river and the ruined bridge serves as a threshold to these realms, and many who have tried to explore the cave's depths have never returned, leaving only whispers of their fate. Some believe that the cave's light is a lure, drawing those who dare to venture into the darkness beneath. Others say it is a beacon, a signal of the Seraphon's power, calling the worthy to discover the ancient secrets of the world.
Despite the dangers, the Cave of Light continues to be a place of fascination for adventurers, scholars, and even the Stormcast Eternals, who remain ever-curious about what lies beneath their watchful gaze. But as with all things in the realms of Sigmar, not everything is as it seems, and the Cave of Light harbors more than just history—it is a living mystery, waiting for those brave enough to uncover its truth.
