Moonrise at the Crimson Cathedral

The Crimson Cathedral is not a place about which many close observations have been made.
One of the few details we possess, however, is the original blueprints from the architects. They completed their design to Evil specifications before it was taken over by the Demon Elves. These designs include a soundtrack. Since certain elements of the spell were not fulfilled by the intended owner taking control, the magic ran a little rampant and took on new life.
According to those who have made it out of the cathedral, it plays heavy metal music during battles.
But otherwise, it plays a haunting tune that begins the exact moment moonlight hits the highest tower of the cathedral. The tune lasts exactly a half an hour, and then ceases. It can be heard up to a mile away if the forest is quiet. The elves who live in the cathedral seem to take it as a moment of contemplation, as they will usually cease all activity during that half hour.
