ENG: You Unlock the races in the tech tree There is a drop box That Can Be Opened From There Select Races

RUS: Вы разблокируете гонки в дереве технологий Существует окно, которое вы можете открыть оттуда Выберите расы

one way i found is using potions(via cheat menu) to change npc's(like cat ears potion, cat tail potion, and fur potion) and getting them to high reputation then asking them to go out into the world and kidnap new slaves, i think it increases the chance they will come back with someone with the same traits
