We all know that the Gods have kept so much from Percy Jackson and his friends. But so much as a whole world of people? The demigods have always thought that they and the gods were the only ones with magic. But, as it turns out, there are wizards and witches as well. Hecate's pet world. But why tell this now? Because a single race cannot stop the evil that is rising. Because there needs to be an alliance. Because, unless both worlds work together and unite, they are doomed.
