Before the Shattering, the Sorcerer-Kings used cruel magics to transform criminals into gigantic workers to slave eternally in the obsidian mines of their overlords. Some time, right before the Shatteringitself, something happened that allowed the jettur to shake off that control and enscone themselves deep inside the mines. As the Shattering shattered the world , the jettur survived and their legends claim they were the first race to set foot on the still burning world.Regardless of their past, the jettur divided themselves between those that wanted to pursue a new way of life and those who wanted the freedom to explore who they were. Their hulking bodies served them well in the aftermath of such an apocalypse and they were well suited for nomadic lifestyles. Many claim a connection to the “Flow” of the world and can temporarily disrupt it with a symbolic stomping, causing a minor localized earthquake.
Mechanicly, The Jettur are half Giants.
