Well, I'll just go ahead and ask a few more questions about the story. I hope you can answer some of them.
1. In your book, Kivoda says that thousands of years have passed since the incident between the two mask makers. Why did the Protectors (and their ancestors) wait so long, why didn't they summon the Toa sooner?
2. According to your book and the online animations, the Mask of Ultimate Power "took control" over Makuta when he put it on his face. Do you know what exactly that is supposed to mean? Is the mask sentient, does it have a mind of its own?
3. Have you ever heard of the name "Kulta"? According to some promotional material, this is the Skull Grinder's proper name, but it has never been used in official media outside of a short description in the LEGO Club Magazine. Do you know anything about this?
4. There are some small differences/contradictions between the book and other media. Some fans are unsure which media they should consider more "canon" in these cases. Can you maybe give us some insight on these, and which version you consider canon?
Here's some of the differences fans have noticed (based on
a post on another fansite, BZPower):
- According to your book, the landscape of Okoto looked very different originally, and the explosion caused by the mask makers' fight changed the island into its current form. In the online animations, the island looks just like today even before that fight.
- According to your book, the ancient city of the mask makers is located in the jungle region. The map on the BIONICLE website shows it located in the water region.
- In your book, Vizuna has a "tail" attached to his spine that contains different sensors. The LEGO toy of Vizuna/the Protector of Jungle has two "sensor tails" attached to his ankles instead.
Well, that turned into a lot more text than I intended.

Again, thank you very much for the time you have taken to answer our questions so far.
