The Under Kingdoms lies to the south of Sacoridia. At the time of King Amigast's reign, there were plenty of disputes between the two countries, usually expressed in acts of piracy against merchant vessels. For now they are at peace, and many denizens can be found moving into Sacor City. One Under Kingdom man, named aus-Corien, sent his son Urath for schooling at Selium, and was a classmate of Karigan's.

A young male from the Under Kingdoms must slay a great animal as a rite of passage into manhood, upon which his cheeks will be tattooed as proof of his feat. One individual with these markings was Gwyer Warhein.
