Kholo (Earth-5875)

Kholo was a heavily populated human Outer colony that was attacked and glassed by the Covenant Fleet of Righteous Vigilance in 2539 during the most violent years of the First Contact War.

First Contact War
Kholo was able to survive the initial decade of the First Contact War, when the Covenant attacked without mercy and with viciousness. However, in 2539, the Fleet of Righteous Vigilance was able to discover the coordinates of the planet's system after its Shipmaster acquired data from a freighter and proceeded to attack it after receiving holy approval from the Covenant High Council.

Battle of Kholo
The planetary UNSC defenses on the planet were considered small and weak by the Covenant, with its scout ships being able to give a critical blow to the humans before the main fleet even arrived. Accompanied by the Prophet of Conviction, the Atoner was ordered to glass the world once the UNSC defenses were mostly destroyed. Using the energy projector of his flagship, the Atoner carved the Covenant symbol of "faith" into Kholo's surface, killing all remaining survivors in the colony.

Post-First Contact War
Later, in 2565, thirteen years after the end of the First Contact War, the Atoner returned to Kholo, in an attempt to find forgiveness for his sins on glassing the planet and searching for a purpose in his life. After wandering in the ruins of the planet for days, he eventually came to find the bones of human civilians who hid within an UNSC bunker. Later, he found kig-yar and humans fighting over relics which he recognized as forerunner. After finding a human survivor, the Atoner brought her with him in an attempt to learn more of the relics.
