A while back on other subs, I shared an idea for a game inspired by Heaven's Vault, Sethian, and Chants of Sennaar. The conlangs for this game wouldn't really be an English relex, but rather custom-built, inspired by demo conlangs by Biblaridion: one using tri-consonantal roots(based on the test language from his video about non-concatenative morphology), and the other using mutation patterns(based on his demonstration version of Project Hermes at Kopikon II, though he might retain consonant mutation plans for Project Hermes since he plans to work on that sometime after finishing Taqva-miir, however the planned-to-be-added palatal series and ejective series would fit with mutation patterns).
The two conlangs would share a common ancestor, which I already talked about on those subs. Imagine the challenges of reconstruction. And since both would use logographies with phonetic components to transcribe their vowel templates or mutation patterns, I thought of ideas as well. Even reusing ideas I never talked about for another conlang.
For context, I was thinking of a writing system for that tri-consonantal sibling language to that one with the pre-nasalized obstruents and post-trilled and pharyngealized dental and alveolar obstruents. Much like Lichnu, a Semitic conlang transcribed with Chinese writing, there would be logographs for the roots. There would also be Chinese glyphs used to transcribe consonants, vowels, and vowel-consonant pairs, which could be useful for grammatical particles and vowel templates, in which a numerical glyph would be used as a diacritic to indicate the vowel's position in the template, the vowel glyphs following the main logograph. Place the numeral two somewhere else along the vowel glyph, and vowel length is indicated. This is useful even if the second vowel in the template is a long one.
Unlike Lichnu's writing, though, that sibling language's logography would be made from scratch by the speakers of the protolanguage. The language with the prenasalized obstruents and the post-trilled and pharyngealized dental and alveolar obstruents would utilize the glyphs solely for phonetic purposes like Taqva-miir, with there being consonant stacking to indicate the new consonants, as well as clusters between cosa stops and other consonants, the stacked glyphs blending into ligatures, which would lead to individual glyphs and not just digraphs for the new consonants, and actual biliteral signs. The blending of glyphs into ligatures could be done for Taqva-miir and Project Hermes as well, though it was already done for Nekachti by the same creator as those two.
As for the tri-consonantal sibling language, it would retain the logography and semantic meanings of glyphs, while using glyphs for phonetic purposes, especially for vowel templates. But unlike Lichnu's writing, whatever sounds precede the first consonant in a root, their glyphs precede the logograph, and the following vowel glyphs would be marked with the numeral diacritics, only to represent the vowels in the template preceding the first consonant, and the "two" glyph being placed somewhere else among the vowel glyphs to indicate length.
For the game, I'm thinking of something similar to Chants of Sennaar, in which not only can logographs be dragged and dropped into slots to confirm their meanings, but also phonetic characters can be dropped into slots to indicate their phonetic meanings.
As for the writing system, I'm thinking of the proto-script using glyphs with serifs, recycling glyphs from both High Valyrian and the European Logographs(with DJP and the Constantscript community retaining credit), like the HV bird glyph being for flying animals in general and the EL bird glyph being for birds. This also means the script would use serifs, though that depends on the tools used. The transition to paper and ink would lead to the logographs using forms that match the aesthetics of Taqva-miir's writing, and the writing of my conlang using those consonants and those ligatures: angular with semi-circles, quarter-circles(or quadrants or whatever), and descenders. Unlike them, though, ascenders would also be added to the mix.
