Borunan is homeland to ogres. It's a barren and hostile region, spread across the Andnemun Desert and the Kelshak Mountains. Before the Sundering, the ogres had a brutal and aggressive culture, dominated by powerful ogre mage lords. Despite their martial might, the ogres rarely threatened the other kingdoms; the Borunan clans considered humans to be unworthy foes and devoted their energy to internal struggles.

Over the course of the Sundering and the Unification, the ogres were brought under Riedran rule and forcibly converted to the Path of Inspiration. Those who resisted were killed or driven into Syrkarn, where they spawned the eneko. Today the ogres are a surprisingly peaceful folk, their warlike culture expunged by the Inspired. Although ogres form the bulk of the population in Borunan, all villages have Chosen overseers, and human and shifter troops are found in the bastion cities.

The people of Borunan tend to be cheerful and straightforward. Feats of strength are admired; a human isn't expected to match an ogre but still earns respect for proving his prowess. Athletic events typically include weightlifting and throwing contests
