High elves 500-700 Dark elves 300-400 Wood elves 200-300
They live waaaayyyy longer. Sothar Sil was born in the early first Era and died in the third. An other example would be Ritemaster Iachesis.
M'aiq is the illegitimate child of Sheogorath (In Skooma Cat Form) and some poor confused Kajiit. Think about it, Ageless Light change of form (This is just a wild guess)
Breten is half-elf race - 110 to 155 years
Redguard - 100 years
Elder Race - ??? years ((Arngeir, Esbern and Septimus Signus) Elder Race might not be a race but just a custom race for these cahrecters as you have noticed they are all old men with customisation options that you can't use in-game but Arngeir and Septimus are 100+ years old
Akaviri (known as the Blades (except Delphine since she is a Breten Blade)) - 100 years
Imperial is half-Alyied race - 100 years
Nord is pure blood human race (relatives are Imperials and Bretens) - 100 years (some have lived until around 150 years like Yurgon wind-caller (only known Nord to have lived to 150 years old))
High ELf/Altemer (Altermar formerlly) - 300 to 350 years
Orc/Orsimer (Cursed Elves by Deadric Prince Malacath (Bosmer formerly) - 100 years
Wood Elf/Bosmer (Altermar formerly) - 250 to ???(350) years (lives in Valenwood which is very plentiful and most of their race are just as old as the High Elves/Altermer as they, unlike the Dunmer and Orsimer, were not cursed by a Deadric Prince and are thus the closest relatives to each other of their race)
Kajiit - ??? (possibly 60 - 85 years as cats in real life don't live very long and so since this is as a humanoid form they gain some hum traits (some people think that they have some Bosmer blood and could explain why most of their race in Elseweyr is shorter than normal)) years
Argonian - ??? (possibly 130 years old as this was the age for a famous Argonianian female that freed her people when they were being enslaved around the time during Elder Scrolls Online and then she joined the allience as the other races of said allience saw her magnificent leadership skills which inspired her people (forgot the name, sorry (she's that Argonian female guildmaster of the warriors guild at one of the major forts in ESO)) (like Achilies led his army and the city of Troy story)) years
Dark Elf/Dunmer (Cursed skin by Deadric Prince Azura (Altermer formerly)) - 270
Falmer (corrupted form) - ??? (less than 300) years (decreased lifespan due to corruption by the Dwemer)
Dwarves/Dwemer - 120 years (only known expetion is that one Dwemer in the spider like mechanical legs (forgot name again, sorry) (like Darth Maul with spider legs on garbage planet from Star Wars: The Clown Wars series or the Dark Souls 1 boss Qualaag or her sister the NPC which you find behind an illusionary wall (you also find her corpse in Dark Souls 3 optional area))
Snow Elf/Falmer (not corrupted form) - 300 to 400 years
Psijiic Monks - ??? years/Immortal (No Damn clue)
Dova/Dragonkind(race) - Immortal (oldest known Dragon except Akatosh is Alduin then in 2nd place is Paarthurnaax, the dragons lived in Akavir rather peacefully and dormant like the dragons in Elsewyr trailer before they went to Atmora which they then flew south three times creating three wars prior it the events of Skyrim, the 3rd war marked the "defeat of Alduin" and the 4th his death at the hands of the Dovakiin in Sovenguard Alduin is as old as Nirn itself but was not givin true life (body) until an unknown year in the world's history more than likely when the dragons after Alduin were created with their physical bodies making Alduin (in Soul) as old as Nirn and Alduin (In Body (Paarthurnaax and other dragons) 6000+ years old))
Knight-Paladin Gelebor and his brother Arch-Curate Vyrthur (oldest living known surviving Snow Elves after the death of the Snow Prince) - these two are the exception as they have been blessed/protected by Auri-El and thus were granted Immortality?, or extended lifespan? thus they are 4000+ years old
M'aiq the liar (Kajiit) - don't even try and guess how old he is. could be a mage like Neloth as Neloth is older than 300+ years old and has outlived the Dunmer lifespan (because he used magic). M'aiq is 1000+ years old (cause he is Akatosh in disgusise (Akatosh has 7 forms - gold dragon, elf hero Auri-El, Old Man, human warrior, 3 unknown (just joking that M'aiq is Akatosh...or is he...))) :-)
Humans - Breton, Imperial, Nord (of Atmora,Skyrim), Redguard, Akaviri (of Akavir) Mer - High Elves/Altmer, Wood Elves/Bosmer, Dwarves/Dunmer, Orcs/Orsimer, Snow Elves/Falmer, Alyied (Cyrodiil and White-Gold tower creators) Beasts - Argonian, Khajiit, Dov/Dova (Dragon/Dragons/Dragonkind of Akavir,Atmora,Skyrim,), (Monkey-race of Akavir), (Naga-race)
human races - 100 years Half-Human races - shared lifespan between both blood closest blood related races (Breten - half-Imperial or half-Nord and one of the pure (non-cursed) Mer race - 110 to 155 years old) Mer races - longer than humans roughly 300 years unless cursed by Deadric Prince or by other means. Beast races - Anomolous (varying non-consistant, each race of the Beast catagory has own seperate lifespan)
Everything above is compiled through various reliable information and easy guessing based on said information on certain races that have no confirmed age to predict the ages of each race, so without a doubt this is the closest to what they actually are. but Meh, you be the judge. Hope it helps.
i may have gotten the dragon age wrong (6000+ years) but im not to sure, just a last piece of edit so no confusion
I thought the dev or a writer established Elves on average have natural lifespan up to 300 years. So I guess without getting killed or sickness, they should fall between 200 - 350. Maybe some will go up to 450 (Much like some humans can live over 100 years old)
and sorry forgot the Vampires - oldest known vampires are Harkon and Searana and her mother (Searana states that she has slept for 2000 years when you find her in Skyrim)
Original Spirits (Magni-di (those that fleed with Magnus during the creation of Nirn gave some power up to create Nirn but stopped unlike the Aedra)/Aedra/Deadra (refused to give up power to create Nirn (Meridia was formerly a Magi-Di)) - Immortal (as old as Atheries)
Almalexia and other two false Gods - they were Immortal but if i remember Azura manipulated their fate so that they all died eventually but there is no dought that they would be Immortal (player actually killed one of these three false Gods in Morrowind i believe)
Shor and Sithis - oldest known entities to exist (older than any being in the Elder Scrolls series and the Original Spirits and potentially Atheries) these two entities are very obscure and unknown and much is left to speculation on what these two beings are (think of them like Yin and Yang, Good and Evil, Life and Death, God and the Devil)
that is possible but only for some High Elves and Wood Elves whom still are considered Altermer which is what all elves were originally before they split up and went to Sumerset Isle (High Elves) and Valenwood (Wood Elves). but its only possible for some of them depending on their health not supported by magical means to extend one's life like Neloth did. other than that the Snow Elves are considered to be the longest living type of eveles and of the races except for Gods and Dragons and so on which are the exception. 450 is their highest life span for the oldest known lifespan.
What do you think?
