Towards the end of Abhorsen, Mogget speaks to Lirael about Chlorr, saying "...even when she was an A--alive." foreshadowing a deeper past. This past is discussed in greater depth in the fourth book in the series, which is entitled Clariel: The Lost Abhorsen. Chlorr, then referred to as Clariel, was the daughter of one of the Abhorsen's children, as well as being distantly related to the King. Her mother ran away from her home; she claims that her brother had been possessed by a Dead creature, and that she had been forced to kill it, but her father refused to believe this. Both she and Clariel had the Fury, but unlike Touchstone, they had a much harder time controlling it.
