After Thrall's triumphant uniting of the clans, the Frostwolves, now led by the orc shaman Drek'Thar, chose to remain in the valley they had for so long called their home. In recent times, however, the relative peace of the Frostwolves has been challenged by the arrival of the Dwarven Stormpike Expedition.

The Stormpike Expedition have set up residence in the valley to search for natural resources and ancient titan relics. Under orders from Magni Bronzebeard, the Ironforge Dwarves were also told to take the land and drive away any who might contest their expedition, with force if necessary. The dwarven presence has sparked heated conflict with the Frostwolf orcs to the south, who have vowed to drive the interlopers from their lands. The Stormpike dwarves sent in an initial, heavily armed expedition, the Stormpike Guard, to search for ancient relics of their past and mine for natural resources.
At this point in time both factions (possibly even the troll faction as well) believe they have historical connections to the valleys and want to take them back.
