The Redanian Secret Service is one of the finest intelligence agencies in the known world (next to the Nilfgaardian and Koviri intelligence agencies). It is headed by Sigismund Dijkstra of Tretogor. They lease quarters on the top floor above the vice-chancellor's offices at the Academy in Oxenfurt which Dijkstra likes to call the Faculty of Most Contemporary History and which Dandelion likes to call the Faculty of Comparative Spying and Applied Sabotage. The service also collaborated with some mages and were implicated in the coup on Thanedd Island, where they sided with the North.
