Most of the galaxy doesn’t live in full daylight. Inner Sphere megacities choke on smog and neon, Frontier settlements cluster under aurora-choked skies, and orbital habitats cycle through long twilight to save power.
Species and communities with low-light vision evolved or engineered eyes for that reality: wide pupils, layered retinas, or subtle bio‑optics that drink up every spare photon.

To them, a Rift-lit back alley, a flickering cargo bay, or a storm-shadowed canyon is perfectly readable. They walk confidently through environments where humans without augmentation lose detail—reading faces, spotting trip‑wires, and watching small gestures that others miss. But kill the lights completely, and they’re as blind as anyone else.

On the street, low-light eyes are prized by scavenger crews, bike gangs, and rooftop messengers who work in the perpetual “almost night” between megacity towers. In the Outer Sphere, many exo-fauna hunters and skyship riggers barely ever see true noon; their world is amber and violet, and their vision has adapted accordingly.
