Summary
CLASS: Forerunner Keyship
DIMENSIONS: 10.8 x 12.4 x 13.1 km
SERVICE PERIOD: ~100,040 BCE - Dec 11, 2552
Commonly known as the Forerunner Dreadnaught, the Anodyne Spirit was the heart of the Covenant holy city of High Charity, serving as the power station for the massive artifical world as well as being the might of the San'Shyuum military during the War of Beginnings. The ship was designed for peaceful purposes, however, serving as one of the ships responsible for reseeding the galaxy following the Great Purification at the end of the Forerunner-Flood War.
Icon of Power
The Anodyne Spirit, also known as the Dreadnought to the Covenant, was originally a Forerunner Keyship, designed to reseed the galaxy with life following the firing of the Halo Array. After the reseeding of the San’Shyuum on their homeworld of Janjur Qom, the ship was taken over by a fragment of Mendicant Bias, who attempted to use the ship to travel to Earth and make amends for taking the side of the Flood during the Forerunner-Flood War. There was a malfunction, however, and the ship crashed onto the surface of Janjur Qom, becoming partially buried after many centuries.
The partially buried Anodyne Spirit was eventually discovered by the San’shyuum and became a point of worship. Dissent eventually grew in the San’shyuum, between the Stoics who wanted to leave the Forerunner ship alone, and the Reformists who wanted to learn from and use Forerunner technology. Eventually the Reformers commandeered the Anodyne Spirit and left the planet in it, taking along a large chunk of the world. The Reformists used the knowledge learned on the ship to form the beginnings of the Covenant religion, including belief in the Great Journey.
Many years later the San’Shyuum met the Sangheili, which kicked off the War of Beginnings. Though the Sangheili were militarily superior, both in tactics and power, the San’shyuum were able to even the playing field primarily through the use of the Anodyne Spirit. Though both sides fought for decades, the San'Shyuum were able to slowly wear down the Sangheili due to the overwhelming strength of that single vessel. Seeing no alternative, the war ended in the Sangheili signing a truce with the San'Shyuum, and as part of the agreement known as the Writ of Union, the Keyship was converted into the power source for High Charity, the new home of the Covenant. For the next nearly 1,700 years the Anodyne Spirit sat as a monument to the power of the Covenant, only being used to support the billions living on High Charity and occasionally being probed for new knowledge using San'Shyuum and Lekgolo worms.
2200 BCE - 2100 BCE
The War of Wills was a fierce and prolonged conflict between two factions of the San’Shyuum: The Stoics who wanted to worship Forerunner technology but never use it, and the Reformists who wanted to take advantage of the incredible Forerunner artifacts around the galaxy.
938 BCE - 852 BCE
The War of Beginnings was an eighty-six year conflict between the San’Shyuum Reformists who escaped Janjur Qom after the War of Wills and the Sangheili species between 938 and 852 BCE.
860 BCE
The Skirmish of the Planet of Blue and Red was a conflict between the San’Shyuum and Sangheili during the War of Beginnings in 860 BCE.
852 BCE - 791 BCE
The Writ of Union not only formed an alliance between the Sangheili and the San’Shyuum, but also commissioned the construction of a great holy city of the Covenant, known as High Charity.
Application of Force
The Anodyne Spirit remained the power source of High Charity throughout the entirety of the Covenant, until its eventual destruction in 2552. After the Flood attacked High Charity at the end of the Battle of Installation 05, the ship was decoupled from High Charity and headed towards Earth, joining the effort to unearth the Portal at Voi. Once the portal was opened, the Anodyne Spirit traveled through it to the Ark, where is transported the Prophet of Truth to the surface. After a brief but intense Battle of Installation 00, the Ark and presumably the Anodyne Spirit, was destroyed by the firing of Installation 08.
