Laura

Laura was the "daughter" of Carmilla, who took her from her true parents and turned her into a vampire many centuries ago. She first meets and challenges Gabriel to a game of supernatural chess, in exchange for passage into Carmilla's castle. After the defeat of Satan, Laura calls to a distraught Gabriel and enlists his aid against the Forgotten One, a mighty Demon that Gabriel released when he slew the Lords of Shadow, during which time, they develop a strong and deep bond which culminated in Laura giving her blood, power and life to Gabriel to transform him into a vampire, attain the strength to defeat the Forgotten One, and subsequently become the Prince of Darkness.
