Dunmer lifespans
Something that is in big debate on every single forum I've seen as of late is the life expectancy of the different races of Tamriel for roleplaying purposes. Can you please elaborate and give us some numbers to work with for each race or at least the Elven races (Altmer, Bosmer, and Dunmer)? – By Nathan Payne / Andrew Hudson
Elves live two to three times as long as humans and the “beast-races” (Orcs, Khajiiti, Argonians). A 200-year-old Elf is old; a 300-year-old Elf is very, very old indeed. Anyone older than that has prolonged his or her lifespan through powerful magic.
Altmer get an additional 100 years thanks to Phynaster.
As we need rough guidelines, a mer is considered a child up to the age of twenty, and adolescence usually lasts until at least the age of eighty. In that time young Dunmer usually behave like illustrated in the Real Barenziah.
