As always the production values are good. This particular track is somewhat low key compared to what I expected for a battle with a wyvern. However, it is very dark and creepy sounding with impending doom building as the creature approaches. Sounds of wings flapping and angelic choirs pervade throughout. I think this could be used with almost any monstrous encounter with a large roaring creature. It could even be used for a dungeon crawl as the party gets close to their final battle . . . the creature waiting to strike.
