Ahhh, you do not know Azshara~
Well, small excursion into.. "What are Naga even?"
Naga have been highborne Elves, actually. Due to stuff, they were cursed to look like this and banished to the dephts. Azshara is the ruler of all Naga, their Queen.. Queen Azshara, ruling from the Naga capital of Nazjatar. That's why you see the name "Azshara" everywhere. I made a point out of giving every hero one ability with Azshara's name in it, just for flavor..
"Azshara's Venom", "Azshara's Malice", "Wrath of Azshara" and "Azshara's Embrace".
