So, yesterday i was thinking a bit about Y'Shaarj and his seven head. There is a thing that was mentioned few times, Wrath of Y'Shaarj. Firstly, in exalted Klaxxi quest (http://www.wowhead.com/quest=31612/shadow-of-the-empire) Kil'Ruk the Wind Reaver said "Great was the Old One, and terrible was His wrath", when i got Klaxxi at exalted i didn't really care about that line. But in patch 5.2 there is a book called "Shadow, Storm and Stone" which describes the purpose of the Mogu and something about their master. Here is the transcript of the second page from the book:
"The beast of seven heads
Fumed Seven breaths.
The land wept shadow
And the swarm blackened the sky.
Supreme was the ancient one:
None dared waken its wrath.
Until the coming of the Storm.
First came thunder, then came Stone
The thunder Storm's voice,
The Stone his weapon.
Lightning seared the sky.
The swarm fled from its light.
Stone struck at the heads of the beast.
The shadow bled into land and sky -
Fear and rage that would not die.
Storm's will was done
Stone's purpose fulfilled."
Here is this "Wrath of Y'Shaarj" mentioned again. So what do you think, it's just a sort of cool word that they added in these two things, or it's foreshadowing of his Seven Head?
