Demons and Mercenaries. Books of Lilith, #1

In a world where encroaching darkness menaces all life, the Cursed Wanderer Lilith - once an elven adventurer - embraces her dark curse. Driven by a longing to find her way back home, she leads loyal mercenaries to confront the spreading shadow. Lilith commands a group of mercenaries: Tuatha Dé Danann Cian, a swordsman apprentice; minotaur Kragor, who provides brute strength; snakeman scholar Sharr; and fallen angel Azael.
Slaves, hoping for escape or favor, serve as support and guides as they venture through dark, dire trials into unknown kingdoms of the Dark Continent. As they battle rising evil, another threat emerges: fomorians seeking revenge against demon kind, guided by their general-gods. Lilith is caught between demons and ancient evil, with limited power and a curse that is threatening to drive her mad.
