There is one song/music in the game which I like very much but I can't find it anywhere.
You will hear it in Cyceal Forest area and Luculla Forest, not sure if anywhere else has it. It's some intrumental music then a man singing something like "oh-yeh-eh-ah-oo".
I even went to Kirill's website to download all the divinity game musics but found no such song. Maybe that's not by Kirill.
