So, this is a micronational conlang, that of Haunsieg. It is a germanic language descended from Old English, with heavy Norse influence, as the shamelessly elaborate culture is also Norse rather than Anglo-Saxon. In short, it is basically a divergent from Old English, as Scots was from Middle English and several pidgins and creoles are to Modern English.
Orthography and Phonology:
Basically everything is pretty straightforward. S represents [s], Ś represents [ʃ], and so on. nothing out of the ordinary. Generally speaking, there are absolutely zero silent letters, with only one official exception, which I will detail later. There are two velar fricatives (ćǥ) , four alveolar fricatives (sśzź),two interdental fricatives (þð] and two labiodental fricatives (fv). Stops follow the same general pattern, with (cgtdpb). Nasals, rhotics and L follow the same pattern as well, as the language includes both voiced and voiceless nasals, rhotics and L. (R) is the same as in English and (L) is always "dark". The vowels have changed little from OE. Also, the language has lost distinction of doubled consonants, which have become fricatives (OE occ becomes Oć), and vowel length, which have a more complicated sound shift to retain distinction between words.
