Despite the advanced civilization that dominates Khorvaire, barbarians live in several places both on that continent and in nearby lands. Human, orc and half-orc barbarians emerge from the Shadow Marches and Demon Wastes. Halfling barbarians ride the Talenta Plains. Human, half-elf and shifter barbarians fill the Eldeen Reaches, though isolated groups of elf, dwarf and even gnome barbarians live there as well. Darguun harbours some bugbear barbarians, and Droaam is home to barbarians of other monstrous species. Some of the wilder warforged that roam the Mournland take up the barbarian class as well.
Beyond Khorvaire, tribes of human barbarians live on the northern shore of Argonnessen and the nearby island of Seren, serving the dragons they revere. Finally, stories abound of children stranded in Xen’drik and raised by wild beasts or savage humanoids, giving rise to another source for barbarian characters.
