The Naga, I believe is Queen Azshara. I am not sure how well into the Lore of World of Warcraft you are, but she was the leader of the Night Elves till the War of the Ancients and the Sundering. After her defeat at the hands of Malfurion Stormrage, and the Great Sundering that sent her and much of her Highborne into the sea. Thus becoming the Queen of the Naga; Empress of Nazjatar.

That is Azshara though. As she and her High Borne were drowning during the Sundering, the Old Gods (probably N'Zoth mostly) whispered to her and offered to save her and her people from death. She accepted and the Naga were born. All that's left from Azshara is her beautifull face, but the rest of her is the embodiment of her rage and hatred towards the surface dwellers who she blames for the defeat during the War of the Ancients. She is presumed to be as powerful as Archimonde (or was it Mannoroth) was.
