The Ferdiad Cycle
The plains Ysgrid are home to a myriad savage tribesmen whose lives are spent in a brutal and unforgiving environment. These tribesmen are collectively known as the Hillpeople or Hillfolk. The northern borders of Aenoria are constantly under attack by raiders of the savages. These raids mostly consist of few dozen warriors that terrorize the farmers and steal living stock. At times an ambitious leader rises and brings several tribes together for a large invasion and sack entire towns.
There are times of peace when some of the tribes barter with the Cerns, bringing exotic animal parts and furs in exchange for weapons and alcohol. Though they are truly barbaric and will torture and maim as likely as trade supplies with an outsider, they have many ancestral ties to the Cerns. Many scholars believe they share a mutual past as their languages have many similarities.
