Ancestral Darkvision is a simple standardized ancestry feat: if you already have low‑light vision from your ancestry, you upgrade it to full darkvision.
Some bloodlines stare into the Rift often enough that their eyes simply stop caring where the light ends. In Starfall, Ancestral Darkvision marks ancestries whose optic arrays, retinal stacks, or mana‑sensitized pupils have adapted to the neon gloom of ecumenopolises, smog‑choked shipyards, and Riftlit void walks.
Mechanics
Geodan engineers who grew up in cavern foundries, Gargo shock troops drilled in unlit kill‑corridors, and Android frames tuned for vacuum hull maintenance all show the trait: their gaze cuts clean through shadow, treating power outages and emergency red‑light conditions as mild inconveniences rather than battlefield hazards.
Hazard Work: Darkvision crews are the default for Metronome maintenance shafts, derelict salvage, and deep‑core mining where lighting is intermittent or sabotaged.
Smuggling & Black Markets: Ebon Syndicate dens and Outer Sphere smugglers design routes with minimal lighting, favoring runners who see perfectly in darkness and don’t need glowlights that show up on sensors.
Urban Survival: In cramped megastructures where power rationing is constant, darkvision is a quiet badge of resilience—your character navigates blackout districts, collapsed tunnels, and unlit maintenance warrens like open streets.
Access to darkvision subtly stratifies labor and danger. Inner Sphere employers justify sending darkvision ancestries into the worst unlit spaces—Rift‑scarred maintenance decks, flooded underhabs, and long‑abandoned Vaelen tunnels—arguing they’re “naturally suited” to it. In the Automaton Concordance, propaganda flips that logic: sensor‑rich synths with darkvision are praised as ideal station wardens and Rift‑gate custodians, proof that organic reliance on light is a design flaw.
On the Frontier, enclaves will sometimes offer better pay or fast‑tracked guild membership to anyone who can work “no‑light shifts,” creating a quiet market for occult surgeries, cybernetic eye replacements, or mana‑burn rituals that mimic this feat’s effect—with all the usual side‑effects and body horror that implies.

Ancestral Darkvision is a tiny mechanical upgrade with huge atmospheric payoff in Starfall: it says your lineage was forged in places where the lights fail first—and you adapted instead of waiting for someone to fix the breakers.
