Supernal Chorus

From Halopedia, the Halo wiki

The construction of High Charity over Tuluk'katho, based around the derelict Fortress-class vessel of Forerunner origin discovered in orbit there.

The Supernal Chorus was an array of mobile foundries, active during the earliest years of the Covenant. During the First Age of Reconciliation, they were responsible for the construction of High Charity, based on the designs laid out by the Minister of the Hearth Laka Mowai and the First Assembled Choir of Builders.[1][2]
