Like all other Agori, Kirbold came into being on Spherus Magna, where he spent his early life in the army of the Element Lord of Ice. Kirbold later participated in the Core War following the discovery of Energized Protodermis in the planet's Core. However, the substance was highly unstable and led to The Shattering occurring as a result of the extensive mining resulting from the war. Kirbold was able to take shelter during this cataclysm and ended up being kept on Bara Magna; unlike a number of unfortunate other warriors who were trapped on Bota Magna.
