"Firbolg tribes cloister in remote forest strongholds, preferring to spend their days in quiet harmony with the woods. When provoked, firbolgs demonstrate formidable skills with weapons and druidic magic (VGM p105)."
Firbolg are an extremely rare race on Iyvis, and it is even rarer for them to be seen outside of their tribes. They live a mostly nomadic lifestyle, caring deeply for nature and the world around them. They stick to small tribes of rarely more than 50 Firbolg, and have extremely secluded lifestyles.
Firbolg rarely leave their tribes, but when they do it usually some sort of quest given to them by a higher power, be it the shaman of their tribe or their goddess, Othea. When this happens, they can spend their entire lives outside of their tribe and will rarely return.
