After the Great War between the Black Elementals and the rest of the world, the last good Elementals went into their Eternal Rest. They were few of them left and they broke their bonds with the Witchers after defeating the Black ones. Years later, a crack in the ancient ice echoed through the valleys and villages until the sound reached Kaer Mohren. It was the same time a child entered Kaer Mohren to start his Witcher training. An Elemental woke the moment Geralt of Rivia survived his tests. It was Geralt's mother, a sorceress, who wanted to keep her son safe and found this the only way : she used an old magic spell to bound their powers together from the first time they would meet. It wasn't until Blaviken, Geralt and Eira met each other and the force of their powers united.
