lorum consists of several separate sites throughout Flanders. The central conventum site lies in Arras, about a mile south of the city center. To outward appearances, the conventum is an industrial site for the processing and weaving of flax. Surrounding the complex is a ring of high-quality tenement buildings, which house the covenfolk.

An important secondary site is Palatium Araneae (Spider's Palace), about two days ride north of Arras, which effectively functions as a laboratory site for the magi of Florum. Rozenn Bonisagi and Rhesus Verditii maintain permanent sancta there.

Several minor sites throughout the region serve as sancta for individual magi.
