Some interesting tidbits from "IKnowMoreThanYou" on Reddit:
the originals are really intriguing and really unique - including a real-life legend, some deep-seeded HHN lore, a conceptual prophecy from a far away land, and some mythical/magical creatures never before seen at HHN in this manner
HHN lore sure seems to back up Dr. Oddfellow's carnival. Mythical creatures I assume dragons (really hoping for some Dueling Dragons Easter eggs). No idea on the other two, unless maybe devil emoji is The Jersey Devil? Just something new from a seemingly credible source.
