Oath to Necrosis

In the fractured remains of the Old World, the emergence of the Great Progenitor—a colossal, shifting nebula of sentient light—redefined the peak of human potential through the manifestation of "Vows." These ephemeral, crystalline entities are birthed from the Progenitor's core, immediately drifting across the continents to seek out human hosts whose latent spirit matches their own vibrational frequency. A Vow does not simply serve; it bonds, acting as a loyal, sentient companion that grants its partner supernatural augmentations tailored to their soul's specific resonance. As the human navigates the world, every hard-won victory and philosophical epiphany fuels the Vow’s evolution, causing it to molt into more complex, powerful forms. This symbiotic ascension ensures that as a warrior’s wisdom deepens and their physical prowess sharpens, their Vow transforms from a mere flickering spark into an indomitable avatar of their inner legacy.
