Fabian was born into the wizarding Prewett family, with two known siblings: Gideon and Molly. During the First Wizarding War, his sister Molly married Arthur Weasley, and the couple eventually had seven children. During the First Wizarding War, Fabian and his brother decided to join the ranks of the Order of the Phoenix to fight against Lord Voldemort and his Death Eaters. Their sister does not appear to have been an official member, probably because she had several young children to take care of.
Eventually, however, Gideon Prewett and Fabian were attacked by five Death Eaters, one of whom was Antonin Dolohov. They were described as having "fought like heroes" by fellow Order member Alastor "Mad-Eye" Moody, though both were ultimately killed. Following Voldemort's fall from power, Dolohov, and perhaps others involved in the Prewetts' "brutal" murders, were imprisoned in Azkaban for the crime.
