Crucabena is known to have made all the children in the House of the Hearth fight eachother, not caring if they die. She uses the name "Mother". Her biological daughter is called "Clervie" and to prove that all her children are equal, forced Clervie to also fight the children of the Hearth. Crucabena was the former Knave of the Fatui, before Peruere (arllechino) killed her and took the name. She seems caring and motherly, but is actually very harsh and drives her children to get stronger.
