Fallen Constellia, the literal fallen heavens. Before the song, the celestials and their pantheons lived high in the sky, in a kingdom just out of reach of the world under it. The gods lived atop their kingdom, ruling over Lumen, offering their followers powers beyond imagination. When The-Song came, the heavens drew near, and the celestials found themselves enchanted by the song and its miracles. As the heavens loomed over Lumen, another force found themselves victim to the song's tune; these foreign forces desired this world for themselves. Within a night, the celestials had fallen from their throne and had come crashing down to the world they ruled over. The heavens had collapsed onto the earth, with the celestials gone, there was nothing left to keep the rampant forces of the heavens at bay; large-scale magic had erupted from the ruins, the rampant energy went wild, transmuting the world in unpredictable ways. From the heavens, grave walls were erected dividing the world into four distinct Luminants, each lumen holding its unique property.
Now, millennia later, the people of Lumen find themselves drawn to the heavens. The common folk drifted into the ruins, but quickly were consumed by them. When the heavens fell, the invading forces imbued fragments of their power into the sea to cover the ruins in a thick layer of Void-fog. This fog mixed with the thick mana in the area turned the ruins of Constellia into its unique biome, where rules were overturned and whispers from the fog threatened to swallow travelers whole.
Constellia-Expeditions often proved fruitful, though due to the thick void fog engulfing the biome, travelers often require the use of old world artifacts to safely traverse the area. Fallen Constellia holds many Artifacts and pre-tidal technology; most of what the world knows of magic and Magitech is a result of these expeditions. One Note, the further one gets into the ruins, the longer it takes to travel in or out of them, it seems there is some sort of time dilation affecting the area.
