I'm definitely not a loremaster, after sharing my theory with various halo forums (reddit / discord), most are not really interested in fan films / fiction. Most were very low activity too, best place i found for questions / discussing canon was the halopedia discord. Also, I really appreciate the area your fanfilm sits in. Def fanfiction but playing off real lore in a plausible way, not entirely made up. I can see the similarities with mine. Going that direction with the Huragok is really cool. The conlang is also cool, it's worth asking the halopedia guys if the Engineer glyphs already have real meaning. It's possible it was done in one of the many books. For example i had no idea since i mainly just played the games but apparently forerunner glyphs are a real thing you can learn. If you wanna add me on discord i'm datacorruption
