Wrath of the Lich King lyrics

Hello, is this a song or just a cinematic?

The lyrics are missing for the song in the cinematic:

An karanir thanagor
Mor ok angalor
Mor ok gorum
Pala uh'm ravali ah'm

Ballog a'l enthu
Korok an boda
Ha, ma
Da, ma

Erigo eo draco modo
Mor ok gorum pala'ahm
Mor ok croval angalor
Thanagor

Mor ok gorum
Pala ah'm raval
Specto su praesenti
Caligo caelum

Mor ok croval anga'lor
Karanir thanagor
Karanir thanagor

With a confirmed translation that goes:

Long live the king,
May he reign forever.
May his strength fail him never.
First in battle last in retreat.
Even in death

Raise this dragon now
May his strength fail him never
May his reign last forever
King
May his strength fail him never
See his power darken the sky
May his reign last forever
Long live the King
Long live the King

And I believe the language will be Latin mixed with a fictional language in WoW, or if there's anything like that in the database.

And if this is to be converted into these lyrics instead, the best video link would be: https://www.youtube.com/watch?v=3m51oKG3BKA

I also see there's this version: https://lyricstranslate.com/en/Blizzard-Entertainment-Invincible-lyrics....
Which has the lyrics I posted above; however, I do not think this cinematic is considered a song.
