Thunderlord clan (film universe)

The Thunderlord clan, in the face of Draenor's hardships (longer winters, short springs and summers, a shortage of game to hunt) initially refused to join Gul'dan's Horde, believing that the clans united would over hunt an area and lead to nothing but quarrel. However, in time the Thunderlord would join the Horde, and while there was an initial quarrel, the fighting would stop, as each clan took to sharing what they knew, and unity between the orc clans would shape.
