The Choir of Solumbra is a coalition of Void Priestesses that worship the dying Void Sun Ataraxis, one of the last remaining artificial suns created by Isame of a Thousand Eyes, spared from the destruction of The Devouring of Heaven.
Void Priestesses paradoxically revere the Void Sun while praying for its annihilation, which they believe will offer salvation to the Remnants who are willing to enter The Shores of Entropy.
