Atmospheric dark ambient. It’s like a movie soundtrack and spans a wide range: creepy, eerie, wondering, whimsical. Makes my imagination run rampant.
I’m currently preparing to GM a Mörk Borg adventure and this is an amazing soundtrack to that setting. It’s dark enough to fit the grim world, but also has so much more layers than just the usual doom metal soundtrack that the canon usually suggests, makes the game atmosphere more versatile.
