After the battle with the Ancestral Witches, she was kept in Oritel's sword for eighteen years in the cold and dark inter-dimension of the Obsidian Circle. She and Oritel were presumably brought together by an arranged marriage, which (revealed in the second movie) is a long upheld tradition in the Domino royal family. Assuming she married at eighteen and gave birth to Princess Daphne around age twenty, and Princess Bloom when she was thirty six, placing her approximate age somewhere between fifty four and fifty six years old. Despite her biological age, Marion still upholds a very youthful appearance, due to being temporarily frozen in the Sword of Domino for eighteen years.
