Vesper was hatched in the lightless pits of the House of the Coiled Shadow, a temple dedicated to the cold supremacy of the Yuan-Ti. Conditioned from birth to be a 'hollow'—a spy capable of mimicking human laughter while calculating the most efficient way to slit a throat—he was sent to the surface to infiltrate a sprawling trade metropolis. He was prepared for the filth, the greed, and the frailty of humanity. He was not prepared for the Carnival of the Sun. Seeing a crowd of strangers unite in a jubilant, clumsy dance broke something inside his engineered mind. The 'Great Cold' of his lineage didn't just thaw; it evaporated, replaced by a desperate, starving need for connection.
He deserted his mission that night, stealing only a sacred ritual instrument—the Resonant Rib-Flute—and vanished into the city’s slums. In the years since, Vesper has reinvented himself not as a destroyer, but as a mender. He views the magical Weave as a living, tattered fabric that humans accidentally snag and tear. To Vesper, a wound isn't just a physical injury; it is a 'glitch' in the local reality. He has dedicated his life to stitching these tears back together, using his flute to hum the melody of the universe back into alignment, much to the confusion of the street urchins and merchants he treats for free.
