Luna Lovegood, the eccentric and beloved character from the Harry Potter series, never married. While she had a close relationship with Rolf Scamander, the grandson of Newt Scamander, the famed Magizoologist, they did not marry.
Instead, Luna married a man named Newt Scamander (the original Newt Scamander, not his grandson). The two met while Luna was working at The Quibbler, a wizarding newspaper, and Newt was writing his book, Fantastic Beasts and Where to Find Them. They fell in love and married shortly after, starting a family together.
Luna and Newt's marriage is a testament to their shared love of the extraordinary and their belief in the magical world's potential for good.
