The Streko River (pronounced STREK-oh) is a river on the eastern coast of the Chaska Sea. The river begins in the uplands north of the Arrajan Forest before flowing south into the Nestra River and from there out into the sea.
The Streko River marks the western-most point that the anti-magic fields of the Arrajan Wilds are known to have reached, though for most of recorded history they have stayed at least a hundred miles to the east.
