Isadore Kettering

Isadore Kettering was a Pureblood English Wizard, Auror, and later Head of the Department of Magical Law Enforcement.

A member of the prominent pureblood Kettering Family, Isadore attended Hogwarts and was sorted into Gryffindor. After leaving the school, he immediately set out to become an Auror.

Kettering served as an Auror for several decades, and became known as an accomplished duelist. The rise of the Knights of Walpurgis, starting in 2008, created a wave of hysteria in the Wizarding World. Following the failure of the Ministry of Magic to protect humanity from the Knights' attacks, the Head of the Department of Magic Law Enforcement, Eugene Bootstrap, was fired, and Isadore, a hardliner and no-nonsense Auror, was put in his place.

As Head of the Department, Kettering put into place a new policy of "fighting fire with fire," authorizing the use of the Unforgivable Curses by Ministry Aurors against the Knights. He also preemptively ordered the arrests of dozens of Pureblood wizards and witches who he believed might collaborate with the Knights.

His extremist methods thwarted a few of the Knights' attacks, but ultimately it resulted in the death and injury of dozens of Aurors and hundreds of non-combatants. The wizarding public grew to dislike both Kettering the Ministry.

After the Knights assaulted the Ministry itself, Kettering used the attack to justify seizing complete control of the wizarding government. He placed the Minister of Magic, Esmeralda Arkenstone, under protective custody, and named himself Chief Wizard, granting himself dictatorial powers. Kettering also placed the Muggle Prime Minister, Gerald Tennyson, under the Imperius Curse, and through him, declared martial law in the Muggle World.

Restricting the personal freedoms of the wizards and witches he was supposed to protect, Kettering showed his true colors, revealing to anyone who had any sense that he was a power-hungry dictator. He founded his own secretive group, the Stalwarts, which replaced the Aurors and became a sort of secret police within Britain. They became just as feared as the Knights for the punishments they wrought against those who spoke out against Kettering.

Public support for the Ministry of Magic had never been lower, and the Knights seized this opportunity by holding a massive rally in the streets of London, terrorizing Muggles and fighting off the Stalwarts that attacked them. After attracting hundreds of new followers with his rally, _ began the March on the Ministry. Thousands of wizards and witches assaulted the Ministry of Magic, and met with only minimal resistance from the Stalwarts. Despite his history as a feared duelist, Kettering became fearful as his regime collapsed and attempted to disapparate. He was captured, however, by the Knights, who had seized complete control over the wizarding government.

After weeks of torture by both the Knights and Dementors, Isadore was shown for the last time to the wizarding public, groveling and pleading for his life. He was then publicly executed by _.
