The Hierarchy

The Hierarchy is an ancient organization of demons intent on taking over each City of Power, and thus having control over the entire multiverse.

Leadership
The Hierarchy's leader has not yet been revealed in-game. However, anyone who's read the Fallen Angel comics will already know that the guy pulling the strings is no other than the demon Moloch.

Attempt to take over Bete Noire
In Metaplot Arc 1, the Hierarchy attempted to take over Bete Noire through use of representatives to regulate and oversee all aspects of life in the city. They were able to do this becaus the Hierarchy, over the course of time, had managed to tie its own power in with the Magistrate's, and thus had a life and death hold over him.

Representatives
In order to ensure that their representatives were obeyed and not attacked, the Hierarchy demons used possessed human hosts from various home universes of Bete Noire inhabitants.

The original list of representatives was Ginny Weasley, Eli Wallace, Jim Gordon, Annie Cartwright and Kaylee Frye. Subsequently, Eli Wallace's demon was kicked out, and Eli joined the cast as a PC. He was replaced by Chloe Armstrong. Later, Annie Cartwright was also kicked out, and Annie joined the cast as a PC. She was not replaced.

Kaylee was removed from her position in the city after incidents of excess violence, and Chloe was executed as a spy, leaving only Ginny and Gordon.

The last two representatives died in the invasion from Yellow Springs.

Future Plans
Though the Hierarchy is temporarily beaten, it is not defeated, and will likely make an appearance in future plot arcs.
