Commentary on Noth.

1. Ri-Vis can be translated either to Space-Time, or Existence-Nothing.
2. Qi Bru would be QБ, or qvelexeb, which means 'toward.'
3. The song's quite simple to figure out, if you're me.

“Parth... ph’ ‘vuvulon à krae’...
Ni fa à tur p’à naise...
Là ei-à-no i’lain...
Etym à là-per ‘cos wvi eq à vul.”

That's extremely-contracted Astrozi, which reads like this in the totality.

Parth... phylax uvuvulon h kraelen...
Ni fa h tur pos-h-naise...
Lat ei-h-no iokalain...
Etym h lat-per ucosco wveru eq phylax vul.

That, itself, translates to this in English, which I felt was fitting.

“Letters... in the flowing of the page...
Or trust of unchanging births...
[Or in] void-love, I say...
The paths of changing love are great and in you.”

4. See the starting quote for the fourth section.
5. RI ATN PRIXEM VIS is an abbreviation of the name of God, which itself is generally shortened to Ri-Vis. It reads RI Aremedha Melat Nharma Patu Reordi Ittrv EM VIS. Take Aremedha's words as you will.
