The Sentience (Fractures)

 was the keeper and organiser of the anomaly vault. It spent eons just conversing with droids until Aesino was installed there and conversed with her. When Romana II arrived, the sentience decided to incorporate her as she was an anomaly due to Pandora inhabiting her first body. The sentience liked Romana and tried to split her as Aesino was. Leela helped her to resist the sentience's attacks. (AUDIO: Fractures) The sentience then took Pandora when she entered the Matrix. (AUDIO: Warfare)
