The ROG questline talks a little bit about it: Some pirates were razing small villages and selling the villagers, and it becomes the PC's job to help hunt them down. This was all in Limsa, and the freed slave NPCs are midlanders, 1 miqo'te, and I think 1 elezen? I'd have to check, but I don't think there was any real racial preference.
