There's an organization called 4-H: Head, Heart, Hands, Health
Within 4-H, there is a secret elite supergroup, 5-H: Health, Humidors, Holistics, Ham and Hunger
Within 5-H, there's an honor guard called 6-H: Humanoids, Holograms, Habitrail, Halogen, Hapsburgs and Hopping.
Those within 6-H who are selected as fit join the hidden masters of the whole operation, 7-H: Hippopotamus, Harassment, Huguenots, Hydrogen, Hanky-Panky, Hamfistedness and Hlobane.
The 7-H denies rumors of an elite, immortal set of indestructible illuminati known as 8-H: Harpo, Heshers, Hippocampus, Hourglasses, Homonyms, Hrafnir, Heliotropes and Heckling.
How deep does the mystery go?
