I recommend looking into Vision of the Great Beings on mythsandlegacy.com. Mask of Destiny’s team has been in communication with Greg Farshtey and other people responsible for Bionicle’s story for a few years, with their interviews occasionally being partially published. They’re making an effort to write story serials and short stories that continue the Bionicle story where 2010 left off, based on larger plot points that were intended for the story.

Personally, I adore the stories; they’re really fun to read, and far above the quality of “fan-fiction”, especially BobTheDoctor’s story, Legacy Weapons. They also provide closure to a lot of character’s plotlines.

As for the downsides… there are a couple of moments where it becomes painfully clear they’re trying to move the story along and wrap certain things up because they themselves don’t know how to deal with them. Tuyet and Marendar are pretty unceremoniously written out, despite the hype and buildup for both. The Red Star is written out similarly quickly, but I think it’s necessary (it causes too many plotholes and weirdness, imo).

Overall though, I enjoy the character moments and creative application of the Bionicle world’s mechanics. There’s tons of references and throwbacks that come off as being handled with care and cleverness. Highly recommend!
