During the early 18th century, the bureaus spread throughout the major cities in the [[Caribbean|West Indies]] varied in size and description; the bureaus in Havana and Kingston held at least one building and had a surrounding courtyard or walls, the Nassau bureau consisted of a small collection of buildings, and the Cayman 'ghost' bureau had no defined buildings or areas to speak of.
After killing the traitorous [[Duncan Walpole]] in 1715, [[Edward Kenway]] recovered and subsequently sold a map detailing the four bureaus' locations to the [[Templars]] operating in the region, unwittingly putting the Assassins stationed there in danger. Edward eventually traveled to the four bureaus and made amends for disclosing their locations; in doing so, he assisted the bureau [[Master Assassin|Masters]] in various ways, in return for a collection of keys that would grant him access to a set of [[Assassin's Creed IV: Black Flag outfits#Templar armor|Templar Armor]].<ref name="AC4"/>

A bureau leader's chamber was adjacent to the main chamber. From behind a desk, each leader addressed those who would come to speak with them, while also studying and attending to the Assassin Order's operations in that respective city.
Behind the desk were bookshelves and closets, where registries of missions were kept. The books and scrolls the leader had access to were also located in this area.
Across the room, a raised walkway held weapons, books, and other items that could assist Assassins in their missions.
