In the city of Grenowell, or G as most residents call it, the 21st century is thriving. The grass is green, the sky is blue, and the night life is vibrant. However, something about Grenowell makes it different. Its residents share the streets with creatures that are not human. Sea witches have migrated into the lake house neighborhoods, puppets swarm under bridges and into private yards where they are not wanted, and scavengers scurry in the shadows of dark alleyways. Don't worry, these creatures will not harm you. They are not interested in humans. For the most part.
