It plays during events and it's from Nightfall Soundtrack. :O wow
First time the sound designers decided to put GW1 music in GW2, not reworked, just in the same form.

There is a lot of music from GW1 in GW2, some of it is really relaxing to hear when your farming, or just randomly mapping and you hear it, and think wow I remember that from 10 years ago doing x event.
Don't say what you mean, it will get you in trouble.
Yes, definitely not the first music from Guild Wars found in Guild Wars 2.
Here's a list: https://wiki.guildwars2.com/wiki/Soundtrack#Track_listing
I know that there is a lot of Jeremy Soule's music and they're from GW1, but this is the music from Nightfall! :oo That makes this map so special, that even some tracks are from Nightfall. Love it!
