Any Portal in a Storm

Objectives
Slay s to collect 5 Whirlpool Cores.
 * Whirlpool Core x5

Description
Our friends in the Earthen Ring have been trying to open portals back to Stormwind, with no luck. But here tells me he might just have the key.

The crazed water elementals in the nearby Verrall River Delta have been sent into a frenzy. Thordun tells me we can channel their energy into a portal.

I don't understand all this elemental-claptrap, but I understand one thing: killin' elementals and takin' their whirlpool cores. Deliver them to in the courtyard!

Rewards
You also will receive: (at max level)

Progress
Hello,. Kurdran tells me you've got a solution to getting this portal opened?

Completion
My word,. These elemental energies are so powerful, so chaotic - no wonder the Twilight's Hammer has chosen to build their stronghold here!

I should be able to channel these energies into something more benign and productive though. Let's give it a try...
