Thrall (birthname Go'el), son of Durotan, was the Warchief of the restored orcish Horde and ruler of the red land of Durotar in Kalimdor. Before the Cataclysm, he was Warchief of all the Horde, but temporarily gave leadership to Garrosh Hellscream in order to lead the Earthen Ring's effort with Farseer Nobundo against the Twilight's Hammer cult and elemental imbalance afflicting Azeroth.

I am the son of the wind and rain,
Thunder beckons and i heed the call.
If i die upon this day,
In battle i will fall.

Hear me brothers gather up the wolves,
To battle, we will ride.
Wardrums echo the beating heart,
Pounding from inside.

Storm
Black clouds fill the sky.
Earth
I hear my battle cry.
Fire
Thunder will bring forth...
Death
From the power of the horde...
