Data Core

The Data Core was a huge hard drive at the centre of the Library. Felman Lux used it to provide a virtual reality for Charlotte to thrive in. An artificial moon called Doctor Moon transmitted waves to and from the Core in order to keep Charlotte happy. The Library staff later saved themselves into the Core and Doctor Moon also helped them. Donna Noble later got caught up in Doctor Moon and the Core's transmissions when she was being teleported and began to live in the Core. The Data Ghost of Evangelista managed to save herself and she became intelligent, but subsequently became horribly deformed. River Song then freed everyone, except Charlotte from the Core and subsequently killed herself. Evangelista returned to her beauty, and the Ghost Data of Proper Dave, Other Dave and Anita were saved there. The Doctor then saved River's Ghost Data into the Core. The Core now occupies River, Charlotte, Evangelista, Anita and the two Daves. (DW: Silence in the Library/Forest of the Dead)
