Eladrin are the feyfolk, most resembling high elves of yore. They lived mostly in the Feywild which is the place just beyond mortal ken. [Often described as “one Step to the Side”] But the changes within the Aether were even more pronounced there then in the mortal realms and many Eladrin fled into the land to escape the madness that was growing there. Some indeed live in the Citadel [perhaps some sixty or so] The Feywild is a very dark and dangerous place now with firbolg and minions ruling unmasse. Those Eladrin that remain are a race in hiding or slavery.
