Before the time of plants and animals, Earth was completely dark and inhabited by beings we now call 'monsters'. When some voice said 'Let There Be Light' , many monsters died because they could not live in this new light world. Not all died however; some of them hid in caves, and grew stronger. Now, they want to return to the world.
