Unyielding Hierophant

Summary
The Unyielding Hierophant is a Covenant Battle Station located in the Tau Ceti system, which was conquered by Covenant forces in 2530. The station was a rendezvous point for Covenant forces, before they launched their impending attack on Earth. Knowing this, the crew of the Ascendant Justice-Gettysburg decide to initiate a first strike against the enemy. During the battle, the Unyielding Hierophant is destroyed, along with nearly 500 Covenant ships, only 12 of which survived. It stands as a monumental achievement for the UNSC, and a discerning loss for the Covenant.
