Category:Eladrin

Up to 3.5 edition, Eladrin were good aligned celestials from Arborea; beginning with 4th Edition, they are fey creatures from the Feywild.

The 4th edition version are what was originally called a "High Elf" in the original version of Dungeons & Dragons. They look like tall elves with eerie green and blue eyes and usually live in a magical forest land away from all other peoples, even humans. However, some of them materialize in the game worlds if they have been sent on a mission.

Isolde is the only known Eladrin residing in Ravenloft, and she is the leader of the Carnival. She came to the evil realm after the Gentleman Caller and had protected people who have fallen victim to his seductive powers. Originating in 2nd Edition, her backstory establishes her as the celestial version, not the modern fey version, of an Eladrin. Using her in a 4th or 5th edition campaign would require allowing both versions to exist, changing her race to another celestial creature, or significant changes to her backstory (or simply ignoring the nitpicking details).
