In His Shadow
Milwaukee is a city that is kept in perpetual war footing by its new Archon-turned-Prince Mark Decker. They exist under a constant threat of Garou attack, and Prince Decker has founded the Anubi, a group of Archons who specialize in werewolf-hunting. Backed by these Anubi, he declared himself Prince in recent months, and none have said otherwise.
Many Camarilla have fled Chicago for Milwaukee as well: https://in-his-shadow.obsidianportal.com/search?tag=Milwaukee.
