The Claatuvac Guild was an organization of Wookiee cartographers, hyperspace scouts and navigators based out of the city of Kachirho on Kashyyyk. Over the centuries, they had mapped and gathered information on a number of hyperspace routes known only to them. The Guild maintained a base in Tree Vikkilynn in Kachirho; a sealed vault contained the guild's navigation data center, powered independently by a generator. The vault included data input and analysis stations as well as data stacks with information stored in indigenous manufactured HoloGrids.
