Corvus is a broad, stooped Scarabaean whose sun-bleached carapace catches the light in flecks of old gold. Tiny cuts and weather-softened grooves cross his shell, many filled with careful ink marks that map solstices, storm tracks, and leyline crossings. His horn curves forward like a question mark, and his many-jointed hands move with the patient precision of a craftsman aligning delicate gears. He walks with a dry, ticking rhythm, then can unfold his wings in a sudden, startling rush of air. The unexpected detail is a bright strip of blue cloth tied around one hind leg, woven by children from the platform gardens; he mends it whenever it frays, though it is far too small to serve any practical purpose.

Corvus is methodical when recording evidence but unexpectedly impulsive when someone is in immediate danger. He enjoys argument as a way to expose weak assumptions, yet grows uncomfortable when debate turns into public humiliation. In calm company he is dryly funny and curious; after a failed forecast he becomes exacting with himself and refuses easy reassurance.

Corvus grew up among the hanging gardens and rain platforms of the Sunlit Reach, where his family repaired wind vanes and measured the storms by the angle of leaves. As a young observer, he joined the early Sun-Pillar Circle, then little more than local druids and weather-watchers comparing notes. His first serious forecast warned of a destructive squall crossing the upper canopy; several communities moved their gliders and children to shelter in time. The Circle's reputation began with that warning, and Corvus learned how useful knowledge could become dangerous when leaders controlled who received it. Years later, a leyline surge scrambled his readings above High-Arch Spire. Corvus trusted the numbers over a local water-singer's warning and sent a platform crew into a wind corridor. The crew survived, but their glider pilot, his closest friend, was lost in the storm. Since then, Corvus has treated prediction as a duty to communicate uncertainty, not a license to command. He advises regional leaders, trains young observers, and argues inside the Circle between those who want forecasts kept within each settlement and those who favor broad warnings. His current instruments show a repeating disturbance beneath the canopy, but he cannot tell whether it is a natural cycle, damaged infrastructure, or something listening through the leylines.
