The Bloodiest of Battles
In the 9th century, a Dalek reconnaissance scout came to Earth with the intention of claiming the planet for the Dalek Empire. To defeat the Dalek, an army of former enemies banded together. The army fought "the bloodiest of battles" against the Dalek, suffering massive casualties. Finally, the army managed to trap the Dalek in netting and set its casing on fire, destroying it and "only just" won the battle. However, the Kaled mutant inside was not destroyed in the fire.

Division of the enemy
Due to the fear the Dalek had instilled in its enemies, the warriors that would become known as the Three Custodians cut the Kaled mutant into three pieces with the plan to bury them at opposite ends of the world and forever guard the burial sites as a precaution to prevent the Dalek from ever returning. Two of the pieces ended up on an island the South Pacific and Siberia, Russia. However, while crossing the area that would one day become Sheffield, the third Custodian was killed, preventing him from carrying out his task. The third piece of the Dalek was left with the Custodian's body where he fell and remained there for over a thousand years. (TV: Resolution)
