Hirami Underdark

The Hirami Underdark is a massive labyrinth of tunnels carved out below the surface of the continent of Hiram. Their original purpose was to allow easier access to human lands for the giants of Or and to provide the giants with mineral resources. In the wake of the Burning Age, however, they have become a battleground as giants fight against humans, halflings, and tieflings for survival in the tunnels they crafted.
