Azrael

(Apart of 'Angels and Demons', but takes place earlier in the timeline.) there are two Dark Angels. Abbadon, the Angel of Destruction, but there is also his brother. Azrael, The Angel of Death. he and his twin Brother make up God's left hand, and are known for being the ones who operate outside the works of regular Angels. Azrael is the Reaper, the one who watches over the souls who have died. if you die prematurely, you will meet him before you go lights out, and he will explain to you what you are seeing. compared to Abbadon, he is very polite and gentle, but he does have a far more ruthless side, which he only shows to God's enemies.
