Actually, I like this song, too. I firstly heard it from civilization vi and fell in love with it.Tips: it is the earliest written song（with notes） we have found.
The titles' bgm started with this rhythm.And it is also the "spell" asterion told us to summon items.Besides, asterion thanked us with the lyric when we didnt take him to the valley.
I'm not English speaker and I didnt use translator, the sentences maybe confusing…
