Chapter 11 of Mask Maker has been posted, and that's all folks! It's a pretty bittersweet ending...not just for the story, but also for myself, since this is actually the largest piece of Bionicle fanfiction I've completed, and it'll likely be the last (for a good long while at least).
In a sense, this story is an attempt at bringing closure to the somewhat open-ended state in which G1 has remained since 2010, as well as a way of transitioning from G1 into G2 and beyond. That's what it is for me, at least. Thanks to everyone who has read it, and thanks to those who took the time to respond. =)
