These beings are the reason for magic to exist, thats why the General wants to eradicate all of them.
    The general is aware that this also means that he will lose his magic powers

In rare cases they take an apprentice which they call Felagi
    Only one Felagi per supernatural being?
    Similar to Moon Knight (Marvel Comics) 
        Konshu (Egyptian god) who grants supernatural powers to Moon Knight
    Maybe once the Nitas give power to a Felagi they can only grant powers again once the Felagi dies
    Maybe the bad General once was a Felagi and received powers from multiple Nitas
        maybe the Nitas saw potential as he was a good person but the power corrupted him and he became too powerful
            the Nitas then decided that no mortal being should ever receive more than one power ever again
