Fabian Prewett (d. 1981) was an English pure-blood wizard and the brother of both Gideon and Molly. Fabian was a member of the original Order of the Phoenix. He and his brother fought in the First Wizarding War, both were murdered by five Death Eaters before the war's end.[3]

Biography
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. Fabian also may have had a big nose.[4]
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.[3]
Eventually, however, Fabian and Gideon 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.[3]
It is unknown how Molly responded to her brother's deaths, but she was most likely heartbroken, given how much she loved her family. She often spoke fondly of them to others.
In 1997, Molly gave Fabian's gold watch to Harry Potter on his seventeenth birthday, as it was traditional to give a wizard a watch when he comes of age. Harry treasured and preserved it throughout the Second Wizarding War, keeping it and wearing it well into his thirties. She also stated that Fabian was not "terribly careful" with his possession, as the watch was dented on the back. Unlike normal watches, it had stars as the clock's hands.[5]

Magical abilities and skills
Magical mastery: Along with his brother Gideon, Fabian was a highly-respected member of the Order of the Phoenix, implying that he was proficient in many areas of magic. Alastor Moody noted that it took five Death Eaters, including the particularly sadistic Antonin Dolohov, to kill Fabian and his brother.[3]
