Perfect theme music for anything that happens as a result of rolling 1. I had a cool tattoo wolf familiar in my friends campaign. Rolled a 1 and shot it dead with my bow. I still cry about it. The church organs perfectly portray that feeling of "oh shit" when someone in the party runs into a trap and gets blown up.
Epic campaign music. I'm guessing you broke it up into parts for a good reason? I just listened to all three parts and when played together they make a wonderful classic arrangement. I'd have posted them as one large track and shrugged about the length, have such a hard time writing music longer than three minutes :p
