They taught Cheri that those so called 'good' Subetans were actually selfish hypocrites who hid their depravity under righteous words. Her parents even helped Darkheart and Liara to attack Shinwa Temple.
Cheri grew up to hate all those who labelled themselves 'good'. She trained under her father to be a full supporter of Darkheart. Under the tutelage of her parents Cheri was growing up to be a perfect 'evil' soldier. However things changed for Cheri following an attack on the Sacred Lands.
Cheri was acting as a scout and watching to see if reinforcements from the sea were coming to help Shinwa. She was walking near the coast when she heard something coming from behind her. Thinking it was an enemy Cheri whipped around and started to attack the enemy in the bush. She stopped herself just in time and was surprised to see a little baby Montre.
It didn't take her long to find out that the little baby was newly orphaned and the evidence as to who had killer her parents was very apparent. Suddenly Cheri was forced to realize what her parents were doing in blind Faith of Darkheart and his cause. Knowing what would happen to the little Montre if she left her there, Cheri fled the Sacred Lands with the Montre .
Still quite young she was ill-equipped to take care of a baby and when a mysterious woman appeared and offered her help she was glad to take it.
Hesitant of this woman at first, Cheri slowly warmed up to her when she found out that Celebony was neutral in the war and just wanted to help those at need the most.
Following much soul searching Cheri decided that she would atone for her past by reaching out to other children like herself in the hopes of stopping children from making the same mistakes she did.
