Elversult, Site of Temple Hill: Among the dark streets of the city move thieves and cutthroats. And they don't like independant operators like Lhasha Moonsliver. But when she hires a former fighter, now the town drunk, as a bodyguard, she gets more than she bargained for. Together they'll have to battle the thieve's guild, the Cult of the Dragon, and other, darker foes. And a fallen man will have to remember the proud warrior he once was.
