Spartakrod (Fae/They) — Today at 4:24 AM
Some lifespans in the galaxies of darkness:
Baseline Humann: 200 without rejuvenants due to generally being hardier than modern humans as a result of the dark age's legacy. With Juvenants, a human can last up to 2,000 years before Nagash's curse causes further Juvenant treatments to fail.
Space Marine: Variable depending on the geneseed, as rule about ten times longer than a normal human with or without Juvenants. Chaos Space Marines who do not become Chaos Warriors still age, they just hide around in weird time wedgies where more important ones will experience bent enough flows of time to live to when they are needed.
Custodes: Custodes don't really age, the perception of losing their edge over thousands of years to become eyes of Terra is mostly mental and cultural.
Eldar: Baseline is about 20,000 years without some sort of outside assistance, Eldar death through Old Age is basically Shyish build up from Nagash's curse until their body fades into a wisp. Eldar mature about ten times more slowly than humans.
Dawi: Roughly half that of the Eldar, they also tend to just...fade one day. They mature faster than the Eldar, though still five times slower than humans.
Ogor: Biologically immortal
Orks: Biologically immortal
Tau: Sixty naturally. Tau reach adulthood twice as fast as humans do, being fully grown before their first decade, being regarded as old at thirty, and generally retiring at forty. They have made strides in life extension through study of the Kroot and human Juvenants.
Votanni: 1,000 naturally, their diminished warp-souls allow them to use Juvenants more often without Nagash's withering.
Adventii: 2,000 Naturally.
Lizardmen: Biologically immortal, some of the eldest Itzecanl characters have been around since the war in heaven, a handful predate it.
Necrons: The necrontyr typically lived to 75 (though the intensity of their parent star's high frequency radiation like x or gamma rays could cut this down drastically) before they developed further technologies, but the Old Ones' ability to simply come back to life was the source of their envy.
Barghesi: Biologically immortal, their homeworld's ecosystem is so hyperhostile that there was no biological benefit to developing teleomere shortening so it just didn't happen.
Kroot: Gained biological immortality from eating Orks and Ogors.
Dragons: Dragon maturation is very strange. They are able to reproduce within 50 years, but they aren't considered true adults until they are nearly two thousand years old. This is complicated by the fact that dragons never stop growing and are shapeshifters, so maturity is entirely measured mentally rather than physically.
Q'orl: The Hive Commanders seem to be immortal, while the queens and kings have never been recorded as having passed of old age, other castes have wildly variable lifespans.
Tyranids: Immortal.
Skaven: Skaven mature at the same rate as actual rats and are ready to reproduce in months after conventional birth, your average clanrat dies in less than a decade, stormvermin generally at least live to be a century old due to the greater effort in keeping them alive as the black furs make up the Skaven middle class, but the rulers of Skavendom can reign for centuries or millennia.
Hrud: The Hruds' seeming immunity to their own time distortion fields suggest they live forever.
Sarhuadin: 2,000 naturally, matures at rates similar to humans.
Ythalnzids: Immortal
Slaugth: Immortal
Rak'Gol: Legitimately impossible to know for certain
Rangda: What the rangda are now is so divergent from what they were when the Slaugth uplifted them that figuring out their "normal" lifespan is pointless.
Vespids: Generally to about 500 years nnaturally, maturing within three.
Drax: 400 years naturally, Mature within 10.
Dracolith: Immortal
Fra'al: Immortal
Thyrrus: ???
Hanallante: Immortal
Reek: Most Reek only live to be about 80.
Khrave: Immortal
Cythor Fiends: Immortal
Ulumeathics: 70 years naturally.
Ogryn: About twice as long as normal humans.
Ratlings: About one and a half times the length of baseline humans
Therianids: Largely the same as baseline humans
Anthrazods: 120 years on average
Galg: 300 years on average
Enoulianns: 50 years on average, generally adults by 5.
Fimir: Biologically immortal
Thunderscorn: Biologically Immortal
Beastmen: Your average Gor is dead by 10 and fully grown in less than a year. Chaos beastmenn can live longer if they gain their gods' favour.
Stryxis: 1,000 on average
Loxatl: 150
Mitu: ???
Osirian Psybrids: ???
