I guess I'll run through this in order as best as I can (or at least, remember):
I personally haven't seen "Trial by Tahu" yet, but it looks like a rather promising short, and the praise given to it by the TTV Crew has swayed me into watching it.
The fact that the "Overlord Makuta" model was released by one of the original set designers was really nice. Hopefully, more will continue to engage with the fans.
On the topic of name pronunciation, I try to stick with the language of which the name is originated. So for most of Early BIONICLE, that would be Māori, and Latin for Late BIONICLE. Here are a couple of names and the way I pronounce them:
Lewa - "leh-wah," not "lay-wah," "lee-wah," or "lew-wah"
Onewa - "oh-neh-wah," not "ah-neh-wah," "ah-nay-wah," or "oh-noo-wah"
Whenua - "feh-noo-ah," not "weh-noo-ah" (while "f" is not the exact pronunciation of the Māori wh, and not the way I pronounce it, it is the closest approximation to the pronunciation of the word for standard English speakers.)
Maxilos - "mah-ksee-los," not "mæ-ksih-los" or "may-ksih-los"
Gelu - "geh-loo," not "gay-loo" or "gee-loo"
Hewkii is the exception to the "ew" pronunciation, not the rule. "Hewkii" is, after all, an anglicized version of "Huki," and is using "ew" as a diphthong, not as a separate vowel and consonant.
I personally regret buying a Copper Mask of Victory during one of the yard sales at Brickfair, as I got a bunch of them during the BZPower fundraiser (which I ended up giving to TTV, but still). I also regret not picking up one of those Manas', but at least I got a Chrome Hau out of it.
BTW, I'm probably gonna sound like a parrot at this point, but it was really nice to meet the TTV Crew, as well as @Shadowgear6335 and @Alieraah. Like I said when I met you there, I've been a fan since 2009, and I really enjoy both of your content. I hope you can find something useful to do with those Skull Scorpio masks!
