What's that song from the Battle of Kaer Morhen?

Just finished the Battle of Kaer Morhen on NG+ and I've been searching for this background song that's been playing throughout the quest. found it on YouTube (description doesn't tell the title, and the comments mention the wrong song) (also searched up the title of the video itself on Spotify, didn't find the right one either). So as a last resort I'm just gonna ask here lmao

here's the song on YouTube so it's easier to recognize for whoever knows the title
