Sorry for not posting in a while.

The other day, I was at another sale, and came across  Bionicle Encyclopedias, one was the first “Official Guide to Bionicle” covering all of Mata Nui stuff, and the other covered everything from Mata Nui to Mahri Nui. (Plus, it also has a lot of stuff that hadn’t been in the big storylines.)  You should definitely get these books!
