So it would seem Oddfellow is now considered yet another Herald, his being of Deceit. At first, I and many others agreed this doesn't make any sense considering both his and Adaru's lore, but I think I may have figured it out:
Oddfellow is the Herald of Deceit, because he is the owner/caretaker of the Lantern. His Deceit is allowing Adaru and the other Icons to believe they're the most powerful, when really they've already been enslaved by Oddfellow and are only giving him more power.
What if at HHN 40, it's not a civil war of Icons to determine who's more powerful, but a revolution against Oddfellow from the old Icons, demanding freedom?
