After the fall of the Aetherii Empire during the Desolate Cascade, those who did not adapt to their new environment became extinct. The now-rare Aetherii High Elves are the most long-lived of any other elven race, with some known to have lived for thousands of years without signs of aging. High elves tend to be self-centered, most likely a result of their inability to present their emotions and warped sense of time due to their long length of life. They rose to prominence during the Age of Elves, and many of them still train themselves in the arcane, learning some basic wizardly magic. High-elven societies no longer exist in mass, most having nomadic lifestyles and able to live for centuries without seeing another one of their kind.
Culture
Aetherii means "Children of the Aether". Unlike most elves, Aetherii elves organized their society along firm and hierarchical traditions. Communities were typically run by members of an esteemed nobility, some of whom could trace their ancestry all the way back to the founding of the Aetherii Empire. Aetherii elf noblility commanded authority through the prestige of their family name or the magical power they held at their behest, a power they often demonstrated through the grandeur of their home.
Aetherii were know to live together in settlements. However, not much of Aetherii society is left after the Desolate Cascade and surviving members of the species might not encounter others of their kind, even for centuries. Since the interest in socializing is rather low among elves, most often, individuals of the race live a solitary lifestyle and only join groups for specific reasons.
