There are three character types in Earth Angels:
Zombie: This is your main character. He or she is a dead body, brought back to life by some means. He or she is intelligent and has a free will. The Zombie comes from all walks of life, but has been resurrected from the dead for one purpose: Protect a selected person or persons from any and all danger. Example: Billy Butcherson
Guardian Spirit: These are spirits sent from Heaven as messengers to awaken the Zombie, and introduce the Protected One(s) to him or her. After the introductions, the Guardian Spirit will act as messenger between Heaven and the Zombie "Earth Angel". The Guardian Spirit cannot take part in the events on Earth. The Guardian Spirit will only warn of "big" dangers that threaten the life/lives of the Protected One(s), from stalkers to large disasters. Day-to-day protection is up to the Zombie. Example: Thackery Binx
Note: Use the Guardian Spirit sparingly. If you wish, you can have the thread-started play the Guardian Spirit. Just tell him/her the name, gender, era the spirit is from, and general personality of the spirit.
Protected One(s): This is the person or persons being protected by the Zombie. It can be one or several (up to three is recommended), but they all fall into the protection of the Earth Angel. This includes family and friends, but is centered on the Protected One(s), themselves. The Protected One(s) is/are ordinary human(s), and may be anyone, famous or not. Example: Max, Allison, and Dani
Other character types:
Ronin Zombies: These are Zombies that are like the Earth Angels in every way, except they have no Guardian Spirit or Protected One(s). These Zombies may latch onto a human, and become his/her protector if they so wish. They may aid in protecting another Zombie's human, or are just passing through. They may, later, be contacted by a Guardian Spirit to become an Earth Angel.
