The Frozen City
Treading the fine line between an independent organization and an arm of the City Watch under the command of the Commissar, a group of martial casters called Goldshield helps prevent crime in the city. Members patrol high-commerce areas invisibly and use such divinations as see invisibility, detect magic (usually for sensing charms and compulsions on shopkeepers), and detect thoughts to catch thieves. Goldshield is based within Dalenguard in Oldtown.
The Shields are administered by a wizard named Renala Hotterin (female halfling wizard). Renala is a secretive figure in the city, although many important people know who she is, few have actually met her. She rarely attends public functions or social events.
