Denizens of the Nightmare Symphony frequently feel like they are being watched. Often because they are. Hamuel is said to have an eye in every shadow.
While this is likely an overstatement, no one can ever quite be sure. Hamuel is responsible for observing the state of the symphony, offering recommendations and if necessary direction to the other elders, ensuring the productivity and effectiveness of heaven, and disciplining wayward angels whose activities are at cross purposes to that of the council of elders.
Hamuel is an Elder from the Nightmare Symphony, they’re not from the core setting, though you are certainly welcome to add them.
