Across the lands of Mantica, there is trade. Markets bustle, coin changes hands and people barter. If you want food to feed your children, you can find someone who'll sell it. If you want silks for your bed, there are places to buy it. These things are obvious, and the wheels of commerce turn ever onward. Yet there are some things that are frowned upon; purchases that, according to those in charge, should not be made. But where there's money to be made, there will be those willing to sell the unsavoury. Beneath the great cities, behind the walls in dark alleys, there are the black markets. Contraband: stolen goods, narcotics, and the like pedalled to those with the money to buy it. But go deeper, go darker, and you find the real items of depravity. Scrolls of foul magic, severed parts of fantastic beasts, curses cast for coin and more. These deep markets are where the Vampire Lord's Necromancers do trade, collecting the spell components that they are unable to gather themselves. And collecting, too, the exotic corpses to be resurrected by their arcane powers. Corpses such as Trolls.
