As a response to the challenges posed by the growing influence of Nyx, the Covenant of the Fallen Light was formed around 500 BCE. This cult emerged in the wake of Icarus' fall, dedicated to exploring lost causes and seeking redemption for past mistakes. The Covenant played a pivotal role in shaping the religious and political landscape, becoming a force that sought to navigate the delicate balance between order and chaos in the Fen Expanse.
