This theme plays a few times throughout the game, when the group reuintes after time apart. There are many cases where the group is fragmented into two, even three parts, and in the fourth season... yikes. Anyway, when folk meet up again, this place.
Careful listeners will detect part of 372 Miles / Storm's Culmination Part 2 in this piece, which is completely purposeful, as that piece contains some themes that felt relevant to tie in with this song (which the player hears first!)
