Death Angels at the Falls.
Death Angels are known in the supernatural world to be judges of the dead. When supernaturals die, they pass judgement on their good and evil acts in life.
Belief System
Supernaturals are wary of them, and never like to talk about them. Ghost whisperers sometimes have interactions with them; for this reason, other supernaturals are wary of them and spirits as well.
Death Angels can also add members to their rank if a certain spirit performed incredible deeds of goodness in life and death: Daniel Brighten became a death angel after helping his daughter.[1]
