Countess Belacqua was the alleged mother of Lyra Belacqua, prior to her discovery of her true parents (Lord Asriel and Marisa Coulter). Lyra was told that Count Belacqua, the countess's wife, was her uncle Asriel's brother, and that the couple had died in an airship accident from which Lyra survived as an orphan. Why Lyra was told this, and whether the Count and Countess were real or fictional, remains a mystery.
