Star Gods are easiest to identify by the color of their robes.
>SERVITORS (Red). The lowest of the orders. They are not even Star Gods proper, but basically biorobots, having just enough rudimentary voodoo to create an aura of awe. They are commonly seen in imperial provinces, acting as decoys, avatars or bodyguards.
>VISITORS (Orange). The lowest of actual Star Gods, armed with strong voodoo but otherwise cheap and fairly expendable clones. They are generally never seen outside of planet takeover operations and Governor holdings.
>OBSERVERS (Azure). The most numerous order, they keep order in imperial provinces. Mastery of invisibility and ghost beams makes them dangerous, but these puppetmasters disdain weapons training.
>SPECIALISTS (Various). Higher castes of Ethereals, like chancellors, scientists or engineers. They know secrets and are never seen outside of closely guarded operations. There is much gradation in these classes.
>PURIFIERS (Black). This order is tasked with ensuring other orders to stay on the true path. They are the only ones with the authority to remove Governors and exterminate worlds.
