At the beginning of creation, there was The Presence, a powerful almighty being that was also known as God and ruled the Kingdom of Heaven. From His ranks of Angels, He created the Pax Dei to maintain the peace of God - hence its name.
The Pax Dei is made up of four orders: the Eagle Host, the Bull Host, the Lion Host and the Human Host. The command over these fell to the Lord of Hosts and special permission was required for an angel to leave their ranks. Ultimate rule over the Pax Dei was to The Presence itself who was known as Him Who Is or as the Most High.
Equipment: The Pax Dei members had access to the advanced magical technology of heaven.
Transportation: Chariots: Flying constructs that allowed angels to travel to distant mortal worlds and dimensions with their vessels being able to brief them on their objectives.
