Knight of Ardougne - OSRS Wiki

The Knights of Ardougne are found in the East Ardougne market place. One is also found in the courtyard of the East Ardougne Castle. Most are found attempting to chase away thieves. They will protect all stalls from the silk stall and up by attacking players that they observe stealing from them. After completion of the Song of the Elves, knights of Ardougne can be found patrolling the streets of West Ardougne as well.
