So after some more searching...
Around himself, Harry could hear a rising crescendo; a sharp note of music, accompanied by mysterious voices whispering incantations and chanting the same repeated phrase of words. "Arahad, yarad! Aermora Bravus! Mors temporis, solnyel khaosu, terminus spatii, myesca can'vic; medevaeris aen operaete! Aurora!"
The Apocryphal Curse also said 'strength through adversity, Aermora Bravus' or something like that, and just now we've been told "Aermora Bravus, novitiate", where Noviate is an actual word meaning the initiate of a religious group.
Mors Temporis is Latin('Death Time', though adding a comma makes it 'Undefined Death' and any subsequent gibberish makes it 'Death of Time', according to google translate), but Solnyel Khaosu is not, Terminus Spatii is romanian for... "space terminus", myesca can'vic is gibberish again, medevaeris is 'you will heal' or 'you will cure' and if you add the aen becomes 'you will heal the cauldrons' but with operaete as well becomes 'you will heal yourself'. according, again, to google translate. also Arahad, yarad turns up as existing individually in several languages, but never both in one.
Bravus superficially seems like it should mean brave; the internet claims it's derivable from the word for a cuthroat barbarian, Pravus; and I have the unaccountable intuition that it's related to birds.
Also, after some searching of words, I discovered that although "Bravus" doesn't show up as a latin word in translate, "RAVUS"(...caps including) does, translating to and from 'Grizzly'(with alternate translations including 'greyish' and 'tawny'.)
Overall, this context sounds like 'Aermora Bravus' means 'Grey Tree'.
Edit: oh and the best translation I have for the quoted thing, put together, is "I see, creation! Grey Tree! Death of Time, [garbled], Death of Space, [garbled], You will heal yourself! Aurora!"
