I so hope we get a void expansion taking place on the moons. Also, what was it about a serpent watching from the outside that those crazy doomsayers in Dalaran were mumbling about?
Edit: Found the quote I was talking about.
An Emerald Dawn.
An emerald sun dawns in the vault of the heavens, but casts no shadow.
The world lifts her voice in terror, but only one can hear her cries.
From the space that is everywhere and nowhere, the crooked serpent feasts on stars.
It has no eyes to see, but it dreams of infinite endings and beginnings.
<Strange glyphs and writing in an unknown language cover the rest of the scroll.>
One of the bosses from the Violet Hold also mentions a blind serpent watching from the endless skies.
