Firbolg

The Firbolg are something of a lowland cousin of the Goliath. These large imposing beings are surprisingly shy. 
They use their inherant magical abilities to keep themselves hidden away from most of the other peoples of Imarith, and as such surprisingly little is known about firbolg culture.
What we do know is that opposed to their more raucous cousins the firbolg are considered a peaceful people, choosing to live in harmony with nature. 

Firbolgs are protectors of the lands in which they call home. They even seem to have the ability to communicate with nature, flora and fauna alike.
