Eladrin

Introduced in the Planescape setting of AD&D 2nd edition and D&D 3rd edition, Eladrin were described as a type of celestial of chaotic good alignment and hailed from the plane of Arborea. In D&D 4th edition, eladrin are instead a race of fey beings, closely akin to elves.

In DDO eladrin are not a race at all. Instead, they are broken up into Bralani Eladrin race and Ghaele Eladrin race for the purpose of classification.
