Daytime Mists

Daytime Mists first manifest in The Well of Ascension as a thickening, river-like fog that begins to linger past dawn, reddened by the rising sun and capable of inducing lethal seizures in non-Allomancers. By The Hero of Ages the phenomenon has escalated: the mists arrive progressively earlier each day, sprout twisting tendrils, and selectively cull the population—yet a single exposure now confers immunity, hinting at a deeper, purposeful design. Across the two books the mists evolve from an unexplained environmental threat into a deliberate, evolving force that shapes human survival and the fate of the world.

The Well of Ascension
Thick gray/white dense mists appearing and persisting into daytime (progressively earlier), flow in large river-like patterns, reddened by morning sun, evaporate in buildings, form shapes/spirits, cause seizures/thrashing/sickness/death in non-Allomancers, longer-lasting away from Luthadel, cause mass starvation fear
The Hero of Ages
Thick gray mists appearing earlier each day even in daylight, twisting tendrils sprout and expand, selectively kill humans via seizures (one exposure grants immunity)
