Servitors are the angels who, well, serve an Archangel and seek to promote that particular worldview... And Word. A Word is... a concept which a Superior (Archangel, Demon Prince) is bound to -- the Archangel of the Wind has weather affinities and can be a bit flighty. The Archangel of the Sword is military, and views himself as a literal weapon of God -- and his people as his own weapons.

Meanwhile, the Prince of Lust has power over the flesh... and the needs of the flesh, at least in certain areas. And the Princess of Freedom has... well, both the irresponsibility of "whatever I want" and general "coercion harms my Word, my power, my self" attitudes.
