No. Beato mentioned something about the Observers being chosen for Order or Chaos, but she wouldn't say anything more than that.

[Ah...!]

But I can tell you how this place works. There are ranks among us here in the city... first, the Pawns. Think of them as Pieces in a game. Then, the Branded. They keep things working around here, one way or another. After them we have the Observers... they are the Messengers' proxys, the ones who play with us in the name of their Masters [Half, bitter smile...]

The Messengers are the ones below the Gods, but I don't know anything more than that.
