Representatives.
Beings who move about representing the will of their superiors, sending out messages or warnings. They were considered as such in this age of humanity.
And in most cases, representatives are relatives of powerful noble families, or the royal family, that work under the king, or the city lord.
With their power, they could better control the target of their purpose, or better represent their superior.
Yet they not only carry their influence and power, but a sign from their superior, that temporarily grants them power above everyone, and below said superior.
A decree, for example.
Such was a representative. But there were also cases, where the representative was no being of power or influence, but a loyal follower instead.
Adonis' case was almost, similar.
