Nadea Rosetta

Doctor Rosetta is a half-elf renowned for her studies into the languages of Azeroth and beyond. She has published numerous articles and her works are included in many tomes found in the Dalaran library, as well as the Scryer's Library. Her greatest accomplishment in her career was the creation of an enchantment that allowed the wearer to understand the languages spoken around them, later on known as the Rosetta Rune. The most common application of the rune is to amulets, or rings.
