Have the game, too, and upon taking a look into the manual (German) again - yes, there are weird things written there.
A few examples (rough translations):
- "the Tohunga worship the Toa out of awe and fear"
- "The Tohunga believe Onua is responsible for creating Earthquakes - a sign that he isn't satisfied with the way the Tohunga care for the Earth"
- "Tahu is the eldest of the Toa, he was created when the planet itself was forming."
- "Lewa is the youngest of the Toa. The Tohunga believe that rain is the result of the eternal conflict between Lewa and Gali, they believe that the thunder is the sound of them fighting."
- "Gali, while still young, is very wise. Since the Tohunga believe that she sustains life itself, they worship her more than any other Toa"
- "While the Tohunga fear Kopaka's great power, they appreciate it for protecting them from Tahu's fire."
- "Pohatu is the ancient Toa of Stone and liked by all other Toa. The Tohunga try to not make him angry because they fear the deadly landslides he can cause."
All in all I get the impression that the Toa were rather treated as gods in the backstory of this game rather than as heroes.
Interestingly the information about the Turaga is correct.
Played the game a couple times, but while it's nice enough it isn't that great in my opinion. I really like that you can actually build the whole island of Mata Nui with the map pieces and everything fits, though - you can actually play the game with the whole island built and get everywhere.
