Vinci Vorpal

Vinci Vorpal was a Pureblood English Wizard. Displaying a prowess in martial magic, he joined the Ministry of Magic after graduating from Hogwarts School of Witchcraft and Wizardry, performing various odd jobs- and mostly doing the organization's dirty work. After some time he was promoted and became one of the first Inquisitors- Wizards who had the grisly job of extracting critical information from prisoners.

Vorpal displayed a sickening knack for this job, and yet, ironically, it was discovered sometime after his appointment that he was actually in league with the Knights of Walpurgis, the very same people he'd been torturing for information. Vorpal promptly fled and joined ranks with his comrades before the Ministry Aurors could aprehend him.
