I hate choosing names for songs, as is evident by some of the titles in this gallery. Fortunately, I discovered that nobody really cares about those, anyway.
So! Here we have a song that plays throughout seasons 2, 3 and 4 of Elancia Chronicles (heck, we may find room for it in season 1 at this rate!) that leads up to some of the bigger fights. During tense standoffs that precede these fights, this music plays, while they characters have it out with one another, and/or whoever they're facing off against. Of course, when the battle begins, one of the boss songs will take over. This doesn't play before every boss, but a few special ones. In season 3, the theme also plays in a dungeon, the Salt Flats , which are not very flat, but certainly salty.
