So, I was questing in Gridania, and I came upon a FATE boss, who was I think level 24. He was a big plant-looking thing, with a vine that stretch upwards really high.

Anyways, the music that played had the same melody as the trademark Final Fantasy chime, just like the log-in screen does, but it was a badass, orchestral version of it. The main part was a violin, and was accented by other intruments, giving it a dark, serious "Battle" sound.

Does anybody know what song this is? More specifically, where I might be able to download its mp3, or even just listen via YouTube?
