The Fallen

The Fallen is a mysterious entity that grows through the latent powers of outcast angels and celestials in the Dreadlands.

Inception
When a celestial or angel has their power stripped from them, they are made mortal and cast into the mortal realm. These celestials lose their memories of who they once were but can only recall their last oath in order to regain their honor - dying in battle against evil. Very few will know one of these outcasts if they ever meet them, as they are forbidden from seeking fame or glory, even though they are often capable leaders they tend to withdraw from the spotlight in situations.

Those outcasts who do not hold to their oaths become twisted and corrupt in the dreadlands and are knowns as 'the fallen'

Witness Accounts
According to those who've seen or interacted with any one of the fallen report their powers are beyond all reasoning, and are overcome with despair. They report mesmerizing and terrifying titan-like creature, humanoid with very odd and terrifying features. The fallen thus may grow much more powerful than they were as celestials though no one seems to know why.
