HEROES. LIGHT and DARK

Well, firstly, the Empire is religiously fanatical; they call their God simply the Almighty to demonstrate his superiority over other gods. Angels are his messengers, and monks are servants of the church. However, within the Empire, the Inquisition and aristocratic representatives hold significant power. And the Royal Guard is the strongest army in the Empire; the name Elite Imperial Cavalry can easily be replaced with Royal Knight.

The Empire's units are generally weak, except for the angels, of course, but it is rich and grows and multiplies very quickly.
