The softly-glittering, rarely-glimpsed shade city of Pangolais is the personal demesne of the mysterious Black Triune, a legendary three-in-one council whose membership into the Umbral Court has remained unchallenged and unchanged since the onset of the Age of Darkness. Their grim enforcer, the soft-spoken vampire general Mykos Roarik, veteran of the Everwar and Right Hand of the Triune, ranges with his Adamant Company far from the shadow-cloaked Uskwood to set the Triune’s will in blood. Those who enter the city without the permission of the Triune must seek out hidden worshippers of Desna or the rare diabolists who make their homes in the haze-shrouded halls of Pangolais.
Senior members of the Umbral Court convene thrice annually in Nidal’s secluded capital, which sprawls below the eternal shadow of the Uskwood. So little light reaches the white-cobbled streets of Pangolais that it is nearly impossible to distinguish day from night, and strangers to the city soon find themselves lost without a guide. Such a service demands outlandish fees, for outsiders are forbidden from walking the winding ways of Pangolais. Here, in quiet cafes and pale gardens, a sinister aristocracy plays dark games of strategy and sacrifice with beings of an unnameable void.
