El Segador de La Habana is the pre-collapse name given to Sister Ines after she poisoned every sister in her convent.
Paz reveals that Ines was not a prison employee or visiting nun. She was an inmate in a Cuban women's prison, while Anton and Paz served as guards.
Before incarceration, Ines poisoned all of the nuns in her convent. News coverage called her El Segador de La Habana, the Reaper of Havana.
Medication had helped stabilize her before the collapse. When the dungeon made ordinary pills seem unnecessary, the group underestimated the danger of removing them. Paz says she has killed many people, including victims whose circumstances the compulsion caused him to forget.
Her later loyalty and bravery do not erase the crime, but leave Carl unwilling to execute her solely as a preventative act.
