Have "The Fallen" actually embraced the darkness? (That would explain the name we gave them.) I got the impression from AnonPig's posts that, once they lost the Traveller, their Fall from grace caused their collapse/the Whirlwind, and their attacks on Earth were an attempt to regain their previous glory. Or maybe they still covet their previous position, but have fallen so far and into corruption, that they can't see how embracing ANY Darkness would be discongruent with a return to the graces of the Traveler?
