The realm of Menonia is accessed by a Quintesson transport device hidden on Cybertron. It seems likely that Menonia in fact exists in an alternate dimension, and whether the name "Menonia" refers to the dimension as a whole or merely one section within it is unclear.
Known inhabitants include: (note: these races are not named in the episode, so take the below designations as descriptors rather than actual race names)
- Dragons: The wizard known as the Golden One can take dragon or human form, these creatures were rarely seen.
- Bird People: Humanoids with the wings and heads of birds, they attacked the castle from the skies, with buckets of quicklime, which killed off the wood-men
- Tree-Centaurs: Strange centaur/ent-like creatures, they are servants of the golden one, but were killed of easily.
- Wood-men: Mara-Al-Utha, The Red Wizard, employed wooden servants that looked like generic Transformers (hinting at his Quintessonian nature). It is unknown if they were animated by technology or magic.
- Reptile-birds: a small dragonish/pterodactylish creature called Sweet Pet served the Red Wizard.
