Ettin

Ettins were a type of giant that are extremely unintelligent and violent in the northern land named Ettinsmoor. They can be described to either having two heads or four arms, but never both.

These creatures were once civilized ones that built ancient cities and bridges around the Wild Lands of the North during the Age of Conquest. But worse, during the Age of Winter, they all started to become uncivilized and became violent with stupidity and vicious temperament.
