Hi all, I like to have ambient background music when I play tabletop games or board games and managed to find the original soundtrack composer's website.

https://mattiaswestlund.bandcamp.com/album/heresy

All the audio tracks from Talisman Horus Heresy are available there and as its the original composer of the work publishing it on his own website I assume its allowed.
