Denk is a region in northern Etha. It was originally occupied by the Filajidin, from whom the Ethains conquered it. The region was then ruled by the Denk dynasty, who drew their name from the region. They would rule the region in its entirety or to a smaller degree until the Second Ethain Civil War.
Denk is a wide peninsula, being surrounded by the Batic Sea to the east and the sea of Velmun to the north. It is mountainous, with the Koulikan flanking it in the south and forming the basis of its border with Egriunda. Moving northwards from the Koulikan, mountains further dissect eastern Denk from western Denk.
