Deffry Vale High School Hat

Deffry Vale High School was a high school in London, England. It was infiltrated by the Krillitanes, who fed the children who attended the school with chips cooked in Krillitane oil, which gave the children's intelligence a significant boost. The Krillitanes hoped to use the super-intelligent children to crack the Skasis Paradigm, which would give the Krillitanes control over the very fabric of reality. Mysterious lights in the sky, as well as a spate of mysterious illnesses and incredibly high results brought the school to the attention of Sarah Jane Smith and Mickey Smith separately.
