Maotic is an... actually it's ok really but it needs to be better. Now that I know somewhat more things about linguistics let's try to re-derive it from first principles.
Common substantives: agróme/agró- "forest", tolet/toléith "tree", taló- "river", namó "sea", ash "ocean", cásper "warm", etkai "island", édris "mountains", elmin(-) "world", cár "land(s)", actó "rift", atlas "great", harad "plains", ablés "storms", cuerol "southern", fír/fíre- "green", alóné "eastern", tárá "far", phato "map". also in "of", ó "to" and á "or".
Proper substantives (probably): Anarós (grassland/prairie?), Mádrós (hills?), Khazad (island), Tabin, Únus (seas), Été (desert); ptolies: Alto, Barith, Sónor, Khélo, Rames Arés, Dorós, Magrós, Mentos, Avalos, Sevros, Ekto Exol (see below), Ekto Mádros (see above), Valias, Andu, Tolao, Ashen (obviously derived from ash "ocean"), Uléné, Tíraló, Malox, Túna, Aspen, Cabotel, Maotel, Akol Bílé, Dalia, Arda; rivers: Ros, Molcrá, Peréx, Málat, Úrol, Mafnil, Exol, Duerol, Septé, Únus, Dekret, Tí, Cabor, Maoth, Dálx, Dzao, Aman; Emaox, Coláera, Ímladris.
-et/-éith should be dialectal variation. -cár alongside ó cár demonstrates both a lack of extensive case inflection (as had previously been assumed) *and* a lack of number. elmin kind of belies even a genitive, so we can assume either nom/acc or nothing at all, and I'm leaning toward nothing at this point—I'll do a full ie-style ablaut system somewhere else.
we already have two -ó words, so river is also taló. the -me in agróme is... a suffix that got generalized, but the compounding stem is still agró-.
ash is the only word with sh, so it's loaned. what is an ocean anyway
we have most things postpositive: sea warm, forest tree, sea storm, plain south, mountain world, rift great, sea east, island tree—but two prepositive; green mountain and far land. the latter is not in a name, so it is more likely to be the usual pattern at least for adjectives. we could say that genitive nouns are postpositive and adjectives are prepositive, so *sea warmth and *rift great...ness?
having c/k both be /k/ is boring. c should be something else, so /kʲ/ regularly but /ts/ in many dialects. fír < fíre with apocope. -s is always syllable-final, so other instances of *s delete. *c before front vowels becomes *s and similarly deletes.
there is one -ol, and about five more in PNs. this is probably a suffix then
The phonology of proto-* obstruents, previously thought to be /p b t d tʼ ɗ k g q/, has thus been amended to /p ˀp pʰ t ˀt tʰ c ˀc cʰ k ˀk kʰ s/ (hi Leiden), which is much more pleasant. I'm inclined to keep the six vowels and the single nasal, because they're unstable, and also I'm going to add original *r to *ʁ.
Vowels might go differently, though. Native words have a/e/i/o with length, and ai, éi (?), ue. ue < *ū, and ai/éi are original diphthongs, so at least one dialect of Maotic lost final -i before consonants, and I guess the other had Vi > V:i or sth.
