Glouroth was a mature adult Shadow dragon that resided in the Deep Wastes between the Lake of Shadows and Maerimydra. He made his lair in the Wailing Cliff, an odd place where the Plane of Shadow bled into the Material Plane. 
Ever slinking in the darkness of his lair, Glouroth generally cloaks himself in shadows to mask his appearance.
Beneath a veneer of charm and serenity Glouroth is a being of roiling hatred and rage. When conversing with others the shadow dragon murmurs soothing platitudes in a hissing whisper, all the while consumed with thoughts of gore and death.
Although Glouroth lived with two groups of Kir-lanan, who both payed homage to him in certain ways, he took little notice of them beyond the offerings the occasionaly brought him.
As the lair of Glouroth resided upon the main route between the city of Maerimydra and the drow outpost of Szith Morcane, this meant that they had to come to a certain number of arrangements concerning their realtionship. This took the form of a pact which meant the drow could garner free passage from both the the kir-lanans and Glouroth through the Wailing Cliff. In addition, priestesses of Lolth knew a further stipulation of the pact that meant they could speak a code word to the shadow dragon telling him "I am a captive, please destroy my captors".
