The southernmost province of the Kingdom of Evenhold, Trowmarch occupies a peaceful and fertile strip of coastal plains and foothills between the Malphigian Sea to the west and the Wyvern Mountains east. Near the center of the province shine the glassy waters of Skyglass Lake which stretch south into the neighboring kingdom of Rinillion.

The province's name comes from a corruption of drow, a reference to the dark elves who lived in the area before the Great Battle of Darkness.
