Kingdom of Gadar-Hos

Also known as the kingdom of chaos, sometimes referenced as the abyss, Gardar-Hos features heavily in myths and legends. I have had trouble finding direct sources referencing this but am including the name due to it prevalence in the lore.

While battles for land raged across the central land, the powerful necromancer of Teratos, Uskuada, plotted in secret. Inviting representatives from Garganesh (now a province of Auquese), Nasgaroth, the Forgotten Territories (Territoire de L’Oubli) as well as the Misty Lands (Territoire des Brumes) to the secret city of Syrn where they hatched a plot. Uskuada wanted to take control of the central lands in to capture the magical energy needed to open a portal to Gadar-Hos, the realm of chaos, and therefore pull the whole world into darkness.
