Each language has a detailed history, with an old-, middle- and new- phase, describing language change comparable to that from Sanskrit to modern Indo-Aryan languages. I have already sketched all of the sound changes, as well as nominal and verbal morphology of each language, but all is liable to change.
For starters, a brief sketch of Language C:
Phonology:
The transliteration is loosely inspired by Biblical Hebrew.
CONSONANTS:
plosives: /p t k b d g/ <p t k b d g>
fricatives: /f θ s z ʃ ʒ x χ h/ <f ṯ s z š ž ḵ x h>
nasals: /m n ŋ/ <m n ŋ>
liquids: /l ɾ/ <l r>
semivowels: /w j/ <w y>
Each of the voiced plosives has a fricative allophone. Plosives occur utterance-initially, and after a homorganic nasal, (plus a homorganic fricative in the case of /d/), otherwise they are fricatives. Fricative allophones can be written
as <ḇ ḏ ḡ> if wanted/needed, because I may make them marginally phonemic (that is still undecided, for example, I may distinguish /zd/ and /zð/), and because it adds to the Biblical Hebrew esthetic.
VOWELS:
high: /i iː u uː/ <i ī u ū>
mid: /eː ɛ ɛː ə oː ɔ ɔː/ <ê e ē ə ô o ō>
low: /a aː/ <a ā>
Schwa is marginally phonemic, usually deriving from unstressed /a/, but not all unstressed /a/ change to schwa.
STRESS:
Placement of stress is phonologically distinctive. It is written with an acute accent, but will be replaced here by the IPA mark since the acute looks ugly in this font.
PHONOTACTICS:
Syllable structure is (C)(w, y)V(C), with an optional /t/ added to it word-finally. Roots frequently do not obey the structure, in which case an epenthetic schwa is added.
a voiceless consonant can precede a voiced consonant, but not the opposite.
MORPHONOLOGY:
There is ablaut, some inherited from PIE, but mostly innovated: the vowel slot can sometimes move between different consonants of a root, although every root still has an inherent vowel. The system is thus far from a true triconsonantal root system.
Morphology:
This is what the descendant of PIE *bʰer- "to carry" looks like in the present tense, just to give you a taste of the language:
singular:
1. munˈḇār /munˈβaːɾ/
2. tinˈḇār /tinˈβaːɾ/
3. ˈbart /ˈbaɾt/
dual:
1. ˈmêlḇəren /ˈmeːlβəɾen/
2. ˈtêlḇəren /ˈteːlβəɾen/
3. ˈlaḇāren /ˈlaβaːɾen/
plural:
1. ˈmêḇəren /ˈmeːβəɾen/
2. ˈtêḇəren /ˈteːβəɾen/
3. ˈbāren(t) /ˈbaːɾɛn(t)/
I would be glad to hear your suggestions regarding the phonology and the orthography.

. I should probably put them in a separate document since there is quite a few sound changes happening!
