History
Archangels are primordial angels, being looked at as Heaven's most "terrifying weapon" and their "fearsome wrath". They're among of the most powerful beings ever created, having to be one of God's first creations. They were put together from the order: Michael, Lucifer, Raphael, and Gabriel. Michael is the mightiest and the most loyal Archangel, Lucifer is the most prideful and avaricious, Raphael was the most ruthless and imperious, while Gabriel was the most mischievous and deceptive. And together, they helped God build the Heavens in ancient times.
