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 to keep Charlotte happy.

The Library staff 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 had also been saved; she became intelligent horribly deformed. River Song freed everyone, except Charlotte from the Core and killed herself. Evangelista was restored to her original appearence, and the Ghost Data of Proper Dave, Other Dave and Anita were saved. The Doctor saved River's Ghost Data into the Core.

After this, the Data Core contained River, Charlotte, Evangelista, Anita and the two Daves. (DW: Silence in the Library/Forest of the Dead)
