Bouldercrag the Rockshaper

Bouldercrag the Rockshaper is the leader of the earthen from Ulduar. He led them to safety after Loken and his iron dwarf army took over Ulduar, and forced the earthen out. He led them to a nearby titan building, that they named Bouldercrag's Refuge. After the raid, many were killed and their numbers are extremely thinned.

He is apparently an ally and friend of renown adventurer Brann Bronzebeard. Brann doesn't seem to want to force the earthen to join the Alliance, especially since they are in such a weakened state. The Ulduar Earthen have lent their aid to Brann many times but are still neutral.

History
While its unknown when the earthen awoke, Loken's army attacked them while they were awake. They could not hold out long against the many iron dwarves attacking them, and eventually lost.

In a desperate attempt to save his people, Bouldercrag lead as many earthen as he could to a nearby titan building. The building was named Bouldercrag's Refuge and is where the Ulduar earthen make their home for now.

Bouldercrag and his people have received help from some heroes that were sent by his friend Brann Bronzebeard, this may help them turn the tides on the iron dwarves at last.
