History

Planar theorists and occultists founded the Brotherhood centuries ago, believing sound and vibration could alter reality and grant immortality.

The Symphony of Transcendence destroyed most of the group and unleashed the Wailing Blight. Its relics, former compound, and surviving enforcer remain connected to that disaster.
