Shan

Scientist Shan was a member of the Kaled Scientific Elite towards the end of the Thousand Year War between the Kaleds and the Thals on Skaro. She worked under Coordinator Davros. She wrote a paper suggesting the Kaled race would need to be re-engineered to survive a post-war Skaro, which she called "The Dalek Solution." (BFA: Davros)

Shan supported Davros's experiments at first, but came to be horrified and objected to them. Davros had her arrested and executed as a traitor. The same happened to Councillor Valron. (BFA: Davros, BFD: Corruption)

She was the daughter of Colonel Krakor, a senior member of the Military Elite who was reported as being killed in battle on the same day that Shan was executed. (BFD: Corruption)
