Something strange is happening in Cannon's Mouth, Ohio. The sky is darker. The air is colder. Violence erupts everywhere. People just aren't themselves anymore, and worse, they don't know why.They don't know because they can't see it.There is a world within our own, occupying the space we perceive as 'open air.' It is populated by various forms of energy. They engulf our senses and enter our bodies, influencing us in ways we can neither control nor understand.It has always been this way, but something is wrong. A destructive force is spreading through the air, corrupting the delicate balance. Only a select few can preserve this balance, but they are severely outnumbered by a horde of hideous creatures.Can they succeed, or will the once peaceful town of Cannon's Mouth fall into darkness forever?
