That is a very educated deduction :P I guess you'll just have to wait and find out.

During my early years of Custom BIONICLE Wiki, I made my own solar system with a planet called Zilon. It's protectors were the Titanium Guardians. That was back in the day, when I still "played" with BIONICLE, and when Niha was a Toa of Light :P

And yes, there is a third piece. It was a forest region known as "Bota Magna".
