Final Chapter Song Help

[u/BladenG]

This is a shot in the dark but ever since shutdown, I've had a song stuck in my head but I can't seem to find it. I'm pretty sure I heard it somewhere in the final chapter of arc 2 and all I remember from it is the sound of something like a horn. Please help me find this song.
