Cavis
From Tardis Wiki, the free Doctor Who reference
Cavisadoratrelundar (or Cavis) and her partner Gandar were agents of Celestial Intervention Agency recruited from the Patrexes College and totally loyal to Lady President Romana. She had been on over 30 missions without regenerating and therefore only had one heart. She also had messy blond hair. Cavis died when she was decapitated and unable to regenerate.
