Baronh: lang of the Abh: Any Details?

Hi!

Recently I came across a conlang used in the anime 'Crest of the
Stars'.  An alien race (who originate from earth but where genetically
engineered), the Abh, speak that language.  It's a conconlang:
conhistory is that it's an artificially purified ancient Japanese that
evolved after the race had left earth.  The language is listed at
langmaker:

Unfortunately, the original grammar is in Japanese and there is not
much about it on the web.  Some interesting grammar notes are here:

Does anyone of you know more about the language?  Especially grammar
and conhistoric development?

Bye,
