Purity of Spirit

Originally called the Joint Venture, the Purity of Spirit was converted into use by the Lekgolo in 2552 by the Sangheili. Externally resembling a regular Covenant CCS-Class Battlecruiser, the Purity of Spirit has had major renovations internally to accomodate a Lekgolo crew.

Construction
Then known as the Joint Venture, the ship was constructed at the Covenant Naval Shipyards at Cloistering Expectancy in 2547. Deployed under the command of Ship Master Zuro 'Zoramee, it saw action in several theatres of combat.

In 2552, the Joint Venture undertook its last missions. In the early part of the year, it participated in the pacification of a minor rebellion by Jiralhanae malcontents on Teash in the Oth Soni System, during which escalating tensions saw the destruction of several other ships and a large number of ground forces. The ship barely managed to survive encounters with Jiralhanae-constructed warships and captured Covenant classifications, retreating to High Charity. It returned two months later as a part of the Fleet of Particular Justice, crushing the Jiralhanae orbital presence and annihilating Teash itself.

Later, in September, the Joint Venture was scheduled to participate in the mission to uncover the Ark. It was present at the Unyeilding Hierophant as it exploded, and was one of a mere handful of ships to survive the detonation. Its Ship Master coordinated the regrouping effort, and sent word to High Charity of the calamity. Too damaged to continue service, it was eventually scheduled for decommissioning at the Sanghelios Orbital Graveyard.

Recommission
The outbreak of the Covenant Civil War changed many things. Unable to afford to lose any of its ships, the Sangheili attempted to recommission the battlecruiser. Eventually, however, it was decided to allow the Lekgolo allies to operate the ship, freeing up Sangheili personnel for other areas. Essentially gutted from within, it was completely overhauled to accomodate a Lekgolo crew.

Rather than being a ship with a crew in a normal sense, the ship is the crew. Lekgolo physiology means that the ships Lekgolo worms have fused into a single hive organism, controlling the ship. Smaller individual Hunter-form Mgalekgolo are carried for ground operations, as well as a Huragok crew for repair and maintenance, but largely the ship runs itself. It holds the recond as the largest single Gesalt form known to the Covenant. To commemorate such an occurance, the ship was renamed by its original Sangheili Ship Master, now a Fleet Master, as the Purity of Spirit.

The Purity of Spirit was tasked with coordinating a number of smaller ships in battle against the Jiralhanae space forces, and proved extremely effective. The lack of need for crew coordination meant that decisions could be reacted upon in split-seconds, and orders did not need to waste time by being given. With faster reaction times than any regular ship in the Separatist fleet, the Purity of Spirit itself decimated enemy ship formations rapidly and efficiently.

After the Covenant Civil War, and the Human-Covenant War, the Purity of Spirit was again retired from service, now serving as the base for a Lekgolo colony on Uhtua, one of Te's moons. It has since come to represent the bond shared between the Lekgolo and the Sangheili, and is used a diplomatic channel between the two species.
