Guild Wars 2

Firstly, I apologize if this is in the wrong section, or if it’s just not right for this forum, but here’s my question:
I was listening to the theme that plays at the end of the quest “A Light in the Darkness” and “The Source of Orr”, during the related boss fights. It’s a big, epic sounding theme that is honestly just awesome. I almost didn’t complete the quests just to hear that theme. Anyway, unless I’m very much mistaken, there’s actually some language being spoken (sung) by the chorus during this song. It’s too obscured by the instrumental parts for me to really hear any of it (not that that’s a bad thing!), but I was wondering if anyone could let us know whether it’s actually some language being spoken.
NOTE: Upon some further research, it seems the official name of this song is “The Seraph”, if that helps.

Don’t know if this is the one you’re looking for, but it was in a related comment when I searched.

There is also a longer version, as I understand it, which would be this. It should, supposedly, also implement some parts which isn’t in the first link.
