In East Freeport: Opal is a Cleric guildmaster.
In West Freeport: Opal is a Wizard guildmaster.
Opal Darkbriar is perhaps one of the strangest oddities in Norrath. According to the tabletop RPG, she is a Dark Elf Cleric guildmaster of the Dismal Rage in East Freeport who uses an artifact to pose as a High Elf Wizard guildmaster of the Academy of Arcana Scientists in West Freeport. The artifact affects her mind if she uses it for too long, making her faction alliances tend more toward the high elf version.
Confusing this matter even further is that one of the historical enemies of the order of Arcane Scientists are the Freeport Militia, who themselves are allied with the evil Opal Darkbriar.
