Nilin is the daughter of the founders of Sensen technology, Charles and Scylla Cartier-Wells. After being in a car crash that injured and embittered her mother, her father designed the Sensen to help Nilin forget her part in it. Nilin becomes a memory hunter, someone who can enter and steal memories: because of skills taught to her by her father, she could also 'remix' them to create a false memory and potentially change a person's outlook and future actions.
