Language
From librae wiki
There is a single [yet] unnamed language in the universe. Its alphabet and phonetics are based on Finnish, minus accented and "borrowed" letters.
This language is used by toponyms and other names. Otherwise for now it's mostly English.
Word construction
Consonants and vowels generally occur in turns. Both can be doubled: consonant/vowel can follow same or other consonant/vowel, but only once and subject to restrictions.
Code
There is a name generation code that should be used as reference to word construction: [:https://gitlab.com/librae/librae/-/blob/master/librae/src/names.rs]
