They Made Their Choice (Horde)

Objectives
Aid First Arcanist Thalyssra.
 * Abyssal Commander Sivara confronted

Description
It wasn't enough for Azshara to break the world. She had to doom the rest of our people here as well!

Those who didn't choose to become naga were stuck in this horrifying half death, left to haunt these drowned ruins.

I am almost afraid to find Sivara.

Wait, did you hear something?

Rewards
You will receive:
 * 22,300 XP
 * +75 reputation with The Unshackled
 * +75 reputation with The Unshackled

Progress
Thrice damned Azshara. Her evil knows no bounds.

Completion
Sivara could have defeated us at any time. Why are they toying with us?

At any rate, champion, again I find myself in your debt. Thank you for helping me, even if the answers we found were more horrifying than I could have anticipated.
