Isn't Opal Darkbriar the delf disguised as a high elf in the magic college in freeport?
edit: i'm such a nerd
Opal Darkbriar is perhaps one of the strangest oddities in Norrath. She is a dark elf cleric guildmaster in East Freeport who uses an artifact to pose as a high elf wizard guildmaster in West Freeport (according to the tabletop RPG). The artifact affects her mind if she uses it for too long, making her faction alliances tend more toward the high elf version.
