Founded late in the Horgon Era, a Mîmêk mining company built it as fortress to cover the advance of mines tapping the Tail of Golruwyrm. This gold vein was so rich that they had been tapping it for centuries. They hit it from the cliffs of Diiv Prok all the way down into the great cavern of Zarag-Gûn. In this area, they ran into trouble. Loosely claimed by the Runelderil Empire, the meager forces of the mining company were forced back. Wanting the support of a bigger party, the mining company requested a settlement charter from Duluk-Zirag. This promised their benefactor a cut of the gold flow and tax revenue of the settlement. In return, the settlement would get the security forces they desperately needed. Conflict between the Runelderil and the people of Sigatharkin went on for many centuries. Long periods of peace followed, yet never lasted more than a few decades. Today, evidence of this conflict lies in ruined blockhouses, forts, towers, trenches, and walls from the shattered gates of Sigatharkin to the once mighty drow city of Ilaleztice.
In the First Epoch, the city had one major church dedicated to Tarâk. In the Onyx Enmity War (915 - 920), it was the urging of the priests of Tarâk that led to the collapse of Zarag-Gûn's ceiling. The stories of today say that Tarâk told these priests that this would end the war with the Runelderil. The collapse of Zarag-Gûn did indeed end the war. It came at great costs though, the roof of Zarag-Gûn was part of the bottom of the Nermanis Sea. When the sea flooded downward, it submerged Sigatharkin, Ilaleztice and other holds for hundreds of miles. Sigatharkin's survivors fled south to Nurum-Maluk. Once a hold of Sigatharkin, it was now a vassal state of the Kuo-toa empire of Âkhi. The population of Nurum-Maluk was more friendly to the refugees than their masters. This eventually gave rise to the Kingdom of Zandûl-Khâl with Nurum-Maluk its capital. Many of those that lorded over Sigatharkin, took positions in this new government.
Today, Sigatharkin is city-sized ruin of Mîmêk architecture. It is a haven for bandits, monsters, and others seeking a place to hide or hunt. By the Treaty of Khelgin-Dûl, with Mulun-Dûna, the Khazarkar Empire, the Âkhi and Zandûl-Khâl as parties, Sigatharkin is not to be resettled.
