Thur Gilc was built by the Krotoan military unit serving under the Covenant general Lukoon. Built to watch for forward elements of demons attacking across the world of Bal-Kriav, in the Tha'lith Front, it was the center of operations for the war against Graz'zt's demon legions.
After the demons were driven out, Thur Gilc became the home of the Tragaran people. In a rugged area, even at its peak under the first Tragaran nation state of Tilnangau (446 LE - 2615 LE), Thur Gilc never grew beyond the size of a small town.
During the rise of the demon empire of Varelay, Thur Gilc became a strategic fortress, guarding the trade and supply lines from the coasts to the Tilnangau capital of Rolipoon.
In 912 LE, captured, Thur Gilc was added to Varelay's holdings.
