Lady Bogle

Lady Bogle, also known as "the Bogle-Banshee", was a banshee and a Lady of the Banshee Court.

Biography
Bogle was born around 1810. Thanks to her great intelligence, she was elected a Lady of the Banshee Court in 1836, marking history as one of the youngest Ladies.

Lady Bogle quickly became notorious for her insistence that the Irish Muggles would soon so outnumber them that they would have no room left in their land, and, barring an extermination of the Muggle population, the Banshees had no choice but to exile themselves to less crowded areas.

She eventually took heed of her own advice and moved to Nepal, where she settled in the city of Kathmandu, terrorizing the local Muggles and even the wizards, who were quite clueless what to do about a Banshee, having never seen one in the flesh.

In 1989, a local wizard managed to banish Lady Bogle into the heights of the Himalayas using a combination of the Silencing Charm and special shields he had himself created. Bogle quickly found herself unable to survive in the snowy deserts, as she got into a fight with a Yeti who ripped her to shreds (as the Silencing Charm had not yet faded away, robbing Bogle of her only means of defense).
