The Fallen are those Daemon who reject their sacred bond with the High People. In defiance of Yevim authority, they cut off their own wings and exile themselves to the world below.
Whispers among the survivors of The Fall speak of these Daemons' treachery, that perhaps they are to be implicated in whatever plot brought about the Magic City's destruction.
The Fallen travel in small circles, seeking allies wherever they can find them. After the Fall, many of their ilk returned to the ruins of the Aerie, to reclaim their homeland.
