 * Heart of the Fury

Description
It is foolish to pursue Gul'dan with magical means alone. But thanks to you we have a prisoner: Garona. If we can break 's mind-control over her, we will learn all his secrets.

I can do it, but I'll need some powerful spell components.

First on the list is the heart of an elemental fury. There's one imprisoned in the center of the Blackrock Foundry. Fight your way in, destroy the furnace, and slay the elemental within.

Rewards
You will receive:

Progress
Elemental "furies" appear to be unique to. It may be something about the primal nature of this world.

Completion
Careful, careful! Set it down gently. I'll take it from here.

The heart of a fury is nothing to toy with.
