Vampires exist among us. They can be your neighbor, your best friend, a teacher for your child, etc. They alter their aged appearance based upon the amount of blood they consume. They move to a new area, drink a lot of blood, and appear young. Slowly they limit their intake of blood and age, right in front of our unsuspecting eyes. After decades, they fake their death, move, and do it over and over again.
Most live quiet lives in an effort to blend in. Some however want power and control.
The Colony is an elite group of vampires sworn to protect the President of the United States from these rogue vampires.
