The Ultimate Vampire Resource and Directory

Personality:

Caelan is strongly pictured as a self-loathing person during his appearances in the series. Although in human form he is seems generally kind and harmless, he quickly becomes obsessive, intense and angry when his feral side is tempted. He blames himself for everything, particularly bad things that happen to Valkyrie. He is shown to be unable to control his obsessive personality when he falls in love with people and reveals during Death Bringer that his former loves have died due to being unable to keep the monster inside him. At one point he reveals that he killed one of Dusk's friends who tried to convince him to stay away from mortals and hide in the darkness, worried that Caelan's behaviour risked the safety of the vampires. This causes him to be exiled and hated amongst other vampires. When he is around Valkyrie he shows undying affection towards her; although, he cannot justify why he loves her when he is questioned, and when Valkyrie breaks up with him he immediately becomes abusive and tries to infect Valkyrie for the sake of their "love".
