Caelum Fallen is the elder son of Amare and Veteris Fallen. When he was sixteen, his parents were separated due to Amare's affairs. Caelum held strong where his brother Anima fell apart. However, he lost his control when Amare died of disease. Anima went to college, but Caelum went straight to work as a businessman's apprentice. He eventually became a CEO and earned a small fortune. Veteris set him up on a blind date with Hira Chandler, and they got married two years later.
Caelum became fast enemies with Contessa Heather, his sister-in-law, but that quickly dissolved once she had her child Fortuna. It came back, though, when Anima became a Vampire. They got in constant fights until Anima and Heather were forcibly cured of vampirism and they left. Veteris went to the hospital four days later, and Caelum and Hira decided to concieve a child. They did so three days later, but minutes after they finished, Caelum got a call from the hospital. Veteris had died of a blood clot. Caelum drifted from Hira, despite her frequent attempts to cheer him up. He was pulled back to reality when Hira birthed her son Santana, and the three live in the Fallen mansion.
