Derek blinked a little and raised an eyebrow. "There are types of slaves. You know that. Domestic slaves who are trained in different domestic chores--physical labor, cooking, cleaning, that sort of thing. Then there's the slaves who see to business or medicine." That was normal at the Hales. But they were't the norm. "Some slaves are bred just to breed more slaves. The Salvatores in town run the breeding colony, and others are bred just to be food for vampires." His tone indicated his disapproval at the latter practices, but he shrugged. "Pleasure slaves are bred to be beautiful, skilled, and pleasing in all ways, but especially sexually. They're luxuries, like gourmet food or an expensive bottle of wine."
