Calida was born in the Roman province of Syria Phoenice in 260 AD during the Crisis of the Third Century, a period of military anarchy and division in the Roman Empire. She was a sacred virgin to Apollo (Orion) until in her 20's she was approached by a Toreador in the guise of the god who took her virginity on the altar of Aphrodite (Venus) and granted her the Embrace.
Sometime after her Embrace, she became the lover of a Ventrue Cainite named Caius. The two settled together in the Roman colony of Aquis Granum (modern-day Aachen, or Aix-la-Chapelle). When Caius met the Final Death, Calida entered a deep depression and fled into the woods around Aachen. It was there that she found Golconda and expanded her mastery of the vampiric discipline Auspex.
She survived to the modern nights.
- Her name is most likely a Romanization of the Arabic name, Khalida, meaning "Eternal".
- According to the chronicler of the Encyclopedia Vampirica, only Helena's beauty surpasses hers.
