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." (AUDIO: 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 her lover Councillor Valron. (AUDIO: Davros, AUDIO: Corruption)

She was a member of the Military Youth from the age of eight.

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. (AUDIO: Corruption)

Personality
Shan was an altruistic and kind soul who was dedicated to helping others. She despised war and, unlike many Kaleds, had no desire to see their Thal enemies wiped out completely. Indeed, she showed disgust at the slaughter of some Thals and attempted to convince Davros that they should make peace with the Thals. She also had a sense of humour that was shown at her reaction to Calcula's hysterics over some rodents that Davros had collected. (AUDIO: Corruption)

Shan was also capable of great courage as was shown when she stood up to Davros when he shouted at her for her relationship with Valoran — she was not even intimidated by his anger. (AUDIO: Davros, AUDIO: Corruption) She also, defiantly, told Fenn to get off her when he tried to 'have a bit of fun'. (AUDIO: Corruption)

Shan was so intelligent that she would've been the head of the Scientific Elite instead of Davros if it weren't for Davros's betrayal.
