Seraphim and Cheribim:

In another dimension God created two races to serve him, the Seraphim and the Cheribim.  The first were warriors, fighting the forces of evil in other worlds.  The second were doctors and servants, providing the soldiers with the services and products they needed to continue the fight.

One day one of the three high generals, Lucifer, took his units and any who would join him to a dark dimension, one ruled by evil, and set up his own kingdom.  Because of this betrayal God demanded that the loyalty of all New angels be tested before they joined the service.  Gabriel had the idea that they could be taken to a neutral world for training and that only those that proved their loyalty would be allowed to return to heaven and receive the Blessing.  God agreed and over 800 thousand Seraphim and 600 thousand Cherabim were sent to earth.

There they formed camps for training and, when some of them were rejected for service, they formed villages to live there lives here.  Those that pass are sent to heaven where they receive the Blessing which let's them tap into a nearly limitless power source.

Seraphim have the power of teleportation and the ability to generate Holy energy which harms evil beings.  Cherabim have healing abilities and the ability to relieve stress and pain.
