The Angels' Flight

A rumor spread by the Eastern realms to give the enslaved Humans hope. That one day, the fabled Angels sleeping within the Ladesch desert will leave their lands to free the East from the Demon Empire's clutch, destroying the unnatural beings who tried to conquer the World.
This idea is encouraged by the Fortern Kingdom to inspire their troops, going even so far as paying artists to draw angels as symbols for their armies.
