Ellasi Craig was a member of the Space Security Service who worked with Anya Kingdom in the Anti-Dalek Force. Anya asked her to look after the Fourth Doctor and Leela to keep the timelines intact. She later brought Leela to the Doctor's TARDIS to collect K9 Mark I. She was knocked out and then accused of sabotaging the engines and being a Dalek agent. However, Anya's interrogation proved the latter to be false. She tried to stop Mark Seven from letting the Daleks onboard but was killed by him. (AUDIO: The Dalek Protocol)
