The Choir Alignment was a valley on the planet Iego between The Scatter and The Boneyard. 100 meters across and shaped like a nine-pointed star, it was clearly artificial in nature. It was said that when one stood in the center, the moons of Iego were arranged in geometric patterns.

The Choir Alignment was a common location for Diathim to congregate, in one of the few times they approached the planet's surface. They would form a column reaching from the valley into the heavens above.
